Duotone Foil Size Guide 2027: Free 2.0, Glide 3.0, Carve 3.0, Crest & Pop
Choosing the right Duotone foil starts with your riding, not just the area printed on the front wing. Your front wing, mast, fuselage/frontpiece and stabiliser or tail all influence take-off, turning, pitch control and pumping efficiency.
Updated for the 2027 foil launch: Free 2.0 remains Duotone's accessible freeride/progression choice; Carve 3.0 SLS and Carve 3.0 D/LAB remain current for carving and performance surf/wing riding. The Glide family has moved on: Glide 3.0 SLS and Glide 3.0 D/LAB replace Glide 2.0 as the latest high-aspect direction. The range also includes Crest SLS, Crest D/LAB and the specialist Pop D/LAB.
This article is the practical sizing and setup guide. For every new model and its construction options, see Duotone Foils 2027 Explained; for mixing old and new components, consult our 3BS / 3BS+ compatibility guide before placing an order.
Quick answer: which Duotone foil should I choose?
| Rider or discipline | Current foil direction | Why choose it? | Setup note |
|---|---|---|---|
| Learning and accessible freeride | Free 2.0 1300 / 1600 / 1900 | Passive lift, low stall speed and forgiving handling | Match PX 195 / 225 / 260 with the respective size; 74cm AL fuselage is a calm learning choice |
| Progressing all-round freeride | Free 2.0 or Glide 3.0 SLS | Free for familiarity and control; Glide 3.0 for noticeably greater pump-and-glide efficiency | Do not transfer Free 2.0 stabiliser pairings automatically to Glide 3.0 |
| Performance winging, waves and freestyle crossover | Carve 3.0 SLS / Carve 3.0 D/LAB | Reactive carving, drive and pop with different construction/connection options | Match the correct Carve tail and fuselage or D/LAB connection |
| Prone, freefly, wake, Foil Assist and surf crossover | Crest SLS / Crest D/LAB | Medium-aspect glide with controlled, agile carving | Check SLS versus D/LAB front-wing and tail interfaces |
| Freeride, light wind, downwind and high-aspect glide | Glide 3.0 SLS | High-aspect efficiency including larger 1250 and 1400 sizes | Choose wing area and matched stabiliser for the discipline and rider |
| Premium freefly, parawing, pumping and downwind | Glide 3.0 D/LAB | High-aspect efficiency, premium construction and smaller performance sizes | Confirm D/LAB/Monobloc tail, frontpiece and 3BS+ requirements |
| Dedicated freestyle and kite foiling | Pop D/LAB | Explosive pop, repop and specialist high-speed response | Specialist 3BS+ and F165 Monobloc tail direction; not a beginner setup |
A sizing rule: the areas are not interchangeable between families. A 1200 Crest, 1250 Glide 3.0 and 1300 Free 2.0 will not all lift, glide or turn the same way. Use rider weight as the starting point, then account for board glide, wind, experience and discipline.
Start with the front wing: latest Duotone sizes
The front wing generates most of the lift, but area alone is not a complete sizing system. Aspect ratio, span, profile and intended speed range can matter just as much. A modern high-aspect front wing may pump and glide efficiently even at low speed, while a lower-aspect progression wing is usually more intuitive for early flight control.
| Current model | Front-wing areas (cm²) | Best buying reason |
|---|---|---|
| Free 2.0 | 1300, 1600, 1900 | Accessible take-off, stability, all-round progression |
| Carve 3.0 SLS | 800, 950, 1100, 1300 | Fast-turning, versatile surf/freestyle crossover |
| Carve 3.0 D/LAB | 500, 650, 800, 950, 1100 | Premium, reactive surf, wing and freestyle performance |
| Crest SLS 2027 | 800, 925, 1050, 1200 | Forgiving medium-aspect prone, wave, freefly and Foil Assist use |
| Crest D/LAB | 550, 675, 800, 925, 1050, 1200 | Premium carving crossover with efficient pumping |
| Glide 3.0 SLS 2027 | 825, 950, 1100, 1250, 1400 | Accessible high-aspect pumping, glide, freeride and light wind |
| Glide 3.0 D/LAB 2027 | 600, 700, 825, 950, 1100 | Premium high-aspect speed, freefly, downwind and parawing |
| Pop D/LAB 2027 | 500, 650, 800 | Specialist freestyle and kite pop / repop performance |
For the detailed 2027 foil launch specifications, performance positioning and build options, read the current Duotone 2027 foil range guide. The Free 2.0 weight-based examples below apply to Free 2.0, not as a universal chart for Carve, Crest, Glide or Pop.
Duotone Free 2.0: the beginner and freeride sweet spot
The Duotone Free 2.0 comes in three sizes:
| Free 2.0 | Surface area | Aspect ratio | Recommended rear stabiliser |
|---|---|---|---|
| 1300 | 1300cm² | 7.2 | PX 195 |
| 1600 | 1600cm² | 7.0 | PX 225 |
| 1900 | 1900cm² | 6.8 | PX 260 |
Duotone has deliberately designed the Free 2.0 around passive take-off, pitch stability and low stall speed.
In plain English, it does not demand advanced pumping technique before it starts working.
Choose the Free 2.0 1300 if:
- you are a lighter rider;
- you already have reasonable foil control;
- you ride in stronger wind;
- you want greater speed and manoeuvrability;
- you are stepping down from a larger progression foil.
Choose the Free 2.0 1600 if:
- you are an average-weight beginner;
- you want a very broad all-round first foil;
- you need early lift without going to the largest option;
- you want something you can continue riding after your first flights.
For a lot of riders somewhere around the 65–90kg area, this is where we would begin the conversation.
Choose the Free 2.0 1900 if:
- you are a heavier beginner;
- your local conditions are often lighter;
- early lift is a bigger priority than top speed;
- you want maximum low-speed confidence.
For riders around 90kg and above who are genuinely learning, the 1900 can make much more sense than trying to copy the smaller foil used by an experienced 70kg rider.
What size Duotone foil for my weight?
| Rider weight | Likely Free 2.0 starting point | Our advice |
|---|---|---|
| Under 65kg | 1300 or 1600 | Choose 1600 for maximum learning ease; 1300 for stronger wind or existing foil skills |
| 65–80kg | 1600 | The broadest beginner/progression starting point |
| 80–95kg | 1600 or 1900 | Choose 1900 if learning ease and light wind matter most |
| 95kg+ | 1900 | Usually the logical Free 2.0 start, particularly for genuine beginners |
Again, do not read those bands as absolute limits. A 90kg experienced foiler may be very happy on a 1300. A nervous 75kg beginner may progress much faster on the 1600.
Which rear stabiliser or Monobloc tail do you need?
Do not assume every current Duotone foil uses the Free 2.0 PX pairings. Carve 3.0, Crest, Glide 3.0 and Pop use different recommended stabiliser sizes and may use different D/LAB or Monobloc tail configurations. See our current Duotone tail guide and check the exact manufacturer's stabiliser recommendation by front-wing size.
For the Free 2.0 the easiest answer is to follow Duotone's intended pairings.
- Free 2.0 1300 → PX 195
- Free 2.0 1600 → PX 225
- Free 2.0 1900 → PX 260
The larger PX 225 and PX 260 are available through the Duotone PX OG rear stabiliser range.
The rear stabiliser does considerably more than simply stop the foil falling over.
It influences:
- pitch stability;
- front-foot pressure;
- turning response;
- pump feel;
- high-speed control.
A larger matched rear wing generally adds more support and calmness. Smaller performance stabilisers free the foil up but demand more control.
Which Duotone fuselage length should I choose?
Important 2027 compatibility distinction: the 60, 66, 74 and 90cm recommendations below describe the conventional Aero AL 3BS fuselage direction. They are not universal fitment instructions for integrated D/LAB or Monobloc-tail builds. The current Frontpiece AL 3BS can connect selected SLS/original front wings to compatible D/LAB/Monobloc tail options, but check the exact complete assembly in the 3BS / 3BS+ compatibility guide.
The Duotone Aero 3BS AL fuselage is available in 60cm, 66cm, 74cm and 90cm lengths.
74cm: best for beginners and maximum pitch stability
The 74cm is the one we would look at most closely for a true beginner.
The extra length makes pitch changes happen a little more slowly and gives the setup a calmer, more settled feel.
Choose 74cm if you want learning to feel easier rather than more reactive.
66cm: best all-rounder
The 66cm is the broad all-round choice.
It retains good control but allows the foil to turn and react more freely.
For somebody who already has basic flights and wants one fuselage with plenty of progression potential, 66cm is hard to argue with.
60cm: advanced and playful
The 60cm makes the foil noticeably looser.
That is useful for advanced wingfoiling, prone and wave-oriented setups.
It is not where we would normally start a nervous first-time wingfoiler.
90cm: primarily the specialist windsurf option
The 90cm fuselage exists for a different job and is mainly aimed at windsurf foiling rather than a normal wingfoil first setup.
What mast length should a beginner wingfoiler choose?
There are competing priorities here.
A shorter mast:
- keeps you closer to the water;
- reduces leverage during mistakes;
- can feel less intimidating;
- works in shallower locations.
A longer mast:
- gives more vertical room before the foil breaches;
- handles chop more easily;
- provides more clearance when leaning into turns;
- has more long-term use for coastal riding.
75cm mast
For many beginners, the Duotone Mast AL 3BS 75cm is an excellent place to start.
It gives enough mast to develop proper foil control without creating unnecessary height.
82cm mast
The 82cm is the stronger all-round progression option.
If you already have good board skills, ride coastal chop or do not want to move masts later, this can make a lot of sense.
90cm mast
For competent riders, extra mast length gives more room in chop and more clearance at speed.
The trade-off is increased leverage, weight and a more intimidating learning platform.
60cm mast
A 60cm mast can be useful in very shallow training environments, behind a boat or for particular early learning exercises, but many riders will outgrow it quite quickly for conventional wingfoiling.
Standard mast or Quick Mount?
Duotone also offers the Mast AL 3BS Quick Mount.
The riding reason to buy it is not that the foil suddenly becomes faster.
The reason is convenience.
The Quick Mount system lets you leave the base plate positioned on the board and attach or remove the foil with the simplified QM connection.
That is particularly useful if you:
- assemble your foil every session;
- have limited van or car space;
- swap foils regularly;
- want to retain your preferred mast-track position.
Current 2027 carbon option: Mast SLS 2.0
For riders moving to the new Glide 3.0, Crest or Pop directions, Duotone has also introduced Mast SLS 2.0 in 76, 84 and 92cm, with the SLS 2.0 Quickmount version available in 76 and 84cm. These are different product sizes from the older 75/82/90cm AL mast comparisons above. Select the mast length based on your riding and check the 3BS+ connection, mast, frontpiece/fuselage and tail combination rather than assuming all Duotone parts work together.
Aluminium or carbon mast?
Beginners do not need a carbon mast.
A good aluminium mast gives a strong, predictable platform and leaves more of the budget available for getting the correct board, foil and wing sizes.
Carbon starts to make more sense when you are sensitive to:
- mast stiffness;
- weight;
- drag;
- pump efficiency;
- high-speed response.
The correct aluminium setup is much better for learning than the wrong carbon one.
When should you move from Free 2.0 to Glide 3.0, Carve 3.0 or Crest?
Once take-offs are reliable and you can control ride height, your next foil should be chosen around the riding you want to do rather than just buying a smaller surface area.
Stay with Free 2.0 for easy freeride progression
Keep Free 2.0 if low-speed support, predictable lift and approachable turns matter more than maximising outright efficiency. It remains a current and valuable foil, particularly when it is matched to your weight and setup.
Choose Glide 3.0 SLS for freeride, light wind and more efficient pumping
Glide 3.0 SLS is the current mainstream high-aspect progression route, with five sizes from 825 to 1400cm². The larger 1250 and 1400 offer useful choices for heavier riders, light wind and disciplines where early lift and long glide are priorities. It is not the same shape or sizing system as Free 2.0.
Choose Glide 3.0 D/LAB for premium freefly, downwind or parawing
Glide 3.0 D/LAB runs from 600 to 1100cm², with a particularly performance-led high-aspect design. Riders buying it should be clear about their start technique and use case, and pay attention to the matched tail and connection system. Do not buy a smaller D/LAB merely because the premium construction sounds better.
Choose Carve 3.0 SLS or D/LAB for more aggressive turning
Carve 3.0 SLS remains a current, versatile carbon surf/freestyle crossover, including a larger 1300cm² option. Carve 3.0 D/LAB goes smaller, lighter and more performance-focused, with a 500–1100cm² range. Carve is the more reactive choice when tight wave turns, drive and freestyle character come before long-distance high-aspect efficiency.
Choose Crest SLS or D/LAB for carving with better connection between waves
Crest SLS and Crest D/LAB bridge carving and more efficient glide. They are particularly interesting for prone, freefly, wake and Foil Assist, or for riders who want manoeuvrability while keeping enough pump-and-glide efficiency to connect sections. D/LAB adds premium construction and smaller 550/675cm² sizes; the SLS starts at 800cm².
Choose Pop D/LAB only for dedicated freestyle
The Pop D/LAB is for skilled freestyle and kite-foil riders prioritising explosive pop and repop. It has dedicated 3BS+ and Monobloc F165 considerations and should not be selected as a normal freeride upgrade.
Buying shortcut: Free 2.0 for approachable lift; Glide 3.0 SLS/D/LAB for high-aspect glide; Carve 3.0 SLS/D/LAB for surf and reactive riding; Crest SLS/D/LAB for carving and connected glide; Pop D/LAB for specialist freestyle. See the full 2027 range guide and the current compatibility guide before ordering the individual parts.
Example Duotone foil setups
70kg complete beginner
- Free 2.0 1600
- PX 225 rear stabiliser
- 74cm fuselage
- 75cm Mast AL 3BS
Easy lift and maximum stability would be the priority.
85kg beginner
- Free 2.0 1600 or 1900 depending conditions
- matched PX stabiliser
- 74cm fuselage
- 75–82cm mast
If the rider is learning in lighter wind, we would lean towards the 1900.
100kg beginner
- Free 2.0 1900
- PX 260
- 74cm fuselage
- 75–82cm mast
Do not undersize the foil simply because you want to avoid upgrading later.
80kg progressing freerider
- Free 2.0 1300–1600
- matched PX stabiliser
- 66cm fuselage
- 82cm mast
This gives a more agile setup while retaining the accessible character of the Free.

Duotone foil sizing FAQs
What size Duotone foil should a beginner use?
For current Duotone setups, the Free 2.0 1600 is a strong starting point for many average-weight beginners. Lighter riders may consider the 1300 while heavier riders and those learning in lighter wind may benefit from the 1900.
Which stabiliser goes with the Free 2.0?
Duotone recommends PX 195 with the Free 2.0 1300, PX 225 with the 1600 and PX 260 with the 1900.
Is a longer fuselage easier to learn on?
Generally yes. A longer fuselage increases pitch stability and makes the foil feel calmer. The Duotone 74cm Aero 3BS AL is the more confidence-oriented choice, while the 66cm is the all-round progression option.
What mast length is best for beginner wing foiling?
Around 75cm is a very sensible beginner starting point for many riders. An 82cm mast offers more progression and clearance for coastal chop, while shorter masts can be useful for specific training or shallow-water situations.
Do I need a carbon mast to learn?
No. Aluminium is a strong first choice and often represents better value. Carbon becomes more relevant once weight, stiffness, drag and performance are priorities.
What is the difference between Free 2.0, Glide 3.0, Carve 3.0 and Crest?
Free 2.0 emphasises easy, reliable freeride lift; Glide 3.0 SLS/D/LAB prioritises high-aspect pump-and-glide efficiency; Carve 3.0 SLS/D/LAB is for responsive wave and freestyle performance; Crest SLS/D/LAB is the crossover for carving plus efficient wave connections. Pop D/LAB sits separately as a dedicated freestyle foil.
Is Glide 2.0 still the latest Duotone Glide?
No. The latest current Glide generation is Glide 3.0 SLS and Glide 3.0 D/LAB. Glide 2.0 may still appear as earlier-generation stock, but this guide recommends the current generation first.
Can I put Glide 3.0, Crest or Pop on my existing Duotone fuselage?
Not without checking the exact year, wing connection, mast, frontpiece/fuselage, hardware and tail. Some SLS/original-to-D/LAB combinations need the Frontpiece AL 3BS, while some newer builds use 3BS+. Check the compatibility guide or send the full part list to The SUP Company.
Can The SUP Company check whether my existing Duotone parts are compatible?
Yes. Send us the model names and years or clear photographs of the connections. Duotone and Fanatic foil generations have changed over time, so checking before ordering can prevent expensive mistakes.

Matching Duotone foil components to your complete wingfoil setup
Foil front-wing area is only one part of the size decision. Match your board litres and length, hand-wing size and actual wind conditions before choosing a Free 2.0 size or moving to Glide 3.0 SLS/D/LAB, Crest SLS/D/LAB or Carve 3.0 SLS/D/LAB. Our complete wingfoil setup guide by rider weight provides practical beginner starting points from 60kg to 110kg+.
If you are considering an 82cm versus 75cm mast, prioritise local water depth, chop, ability and the clearance you need before chasing a performance claim. This page's Duotone mast comparison should remain the brand-specific reference. Also see our UK wingfoiling wind guide for conditions and hand-wing sizing.
Compatibility check: check the precise mast, fuselage, front wing, stabiliser and mounting connection for your model year. Do not assume that a shared Duotone brand name guarantees every component is interchangeable.
