Surfboard Size Chart: Find Your Length and Volume (2026)
Weight and ability matter more than height when sizing a surfboard. Use these length and volume charts to find a board you can actually catch waves on.

How to Use a Surfboard Size Chart
Choosing a surfboard comes down to two numbers: your weight and your ability. Your weight decides how much volume (buoyancy) you need to float and paddle; your ability decides how much you can sacrifice stability for maneuverability. Height plays a smaller role.
The charts below come from published sizing guides. They differ a little, so treat them as a starting range, then adjust for your fitness, how often you surf and your local waves.
Surfboard Length Chart by Weight
This chart follows Surfertoday's board size chart (weights in kilograms; 1 kg ≈ 2.2 lb).
| Board / Level | 45–63 kg (99–139 lb) | 63–72 kg (139–159 lb) | 72–81 kg (159–179 lb) | 81–90 kg (179–198 lb) | 90+ kg (198+ lb) |
|---|---|---|---|---|---|
| Longboard, beginner | 9'2"–9'4" | 9'4"–9'6" | 9'6"–9'8" | 9'8"–10' | 10'+ |
| Longboard, intermediate | 9'0"–9'2" | 9'0"–9'2" | 9'4"–9'6" | 9'4"–9'6" | 10' |
| Funboard, beginner | 7'2"–7'4" | 7'4"–7'6" | 7'6"–7'8" | 7'8" | 7'8"+ |
| Funboard, intermediate | 7'0"–7'2" | 7'2"–7'4" | 7'6" | 7'7" | 7'8" |
| Fish, intermediate | 5'10"–6'2" | 5'10"–6'2" | 6'4"–6'7" | 6'8"–7'2" | 7'6"–8' |
| Shortboard, intermediate | 6'1"–6'4" | 6'3"–6'8" | 6'5"–6'10" | 6'9"–7'4" | 7'8"+ |
True beginners usually start on longboards, soft-tops or funboards rather than fish or shortboards.
Surfboard Volume Chart (Liters)
Volume, in liters, is the most useful single number for sizing. This chart follows Surfertoday's volume calculator, which applies a Guild Factor to body weight.
| Weight | Beginner | Beginner/Int. | Intermediate | Int./Advanced | Advanced |
|---|---|---|---|---|---|
| 50 kg (110 lb) | 39 L | 29 L | 24 L | 20 L | 20 L |
| 59 kg (130 lb) | 43 L | 32 L | 27 L | 22 L | 21 L |
| 68 kg (150 lb) | 48 L | 36 L | 30 L | 25 L | 24 L |
| 77 kg (170 lb) | 54 L | 41 L | 34 L | 28 L | 27 L |
| 86 kg (190 lb) | 60 L | 45 L | 38 L | 32 L | 30 L |
| 95 kg (210 lb) | 67 L | 50 L | 42 L | 35 L | 33 L |
| 100 kg (220 lb) | 72 L | 54 L | 45 L | 38 L | 36 L |
| 109 kg (240 lb) | 83 L | 62 L | 52 L | 44 L | 41 L |
Important: other guides recommend far more volume for true first-timers, roughly matching your body weight in kilograms (for example, about 70–75 liters for a 70 kg beginner), which is soft-top and longboard territory. The "beginner" column above is better seen as a starting point for beginners moving onto smaller hard boards.
The Guild Factor Formula
Weight (kg) × Guild Factor = suggested volume (liters)
| Ability | Guild Factor (Surfertoday) | % of Body Weight (Retailer Guides) |
|---|---|---|
| First-time beginner | 0.50+ | About 100% |
| Weekend / casual | 0.43–0.49+ | — |
| Intermediate | 0.38–0.42 | About 55–60% |
| Intermediate / advanced | 0.36–0.38 | About 40–45% |
| Advanced / pro | 0.34–0.36 | About 34–38% |
Worked example: an intermediate surfer weighing 80 kg (about 176 lb) might ride about 80 × 0.40 = 32 liters on a shortboard. The same surfer as a first-timer would be far more comfortable on a 75+ liter soft-top or longboard.
Fitness, age and how often you surf matter too: if you surf rarely, are less fit or are older, go up a level in volume.
Beginner Board Sizes
For most adult beginners, a soft-top or longboard of about 8 to 9 feet is ideal; lighter riders can start around 7 to 8 feet. One retailer's guide suggests roughly:
| Rider Weight | Soft-Top Length | Volume |
|---|---|---|
| Under 60 kg (132 lb) | 7'0"–8'0" | About 60–80 L |
| 60–85 kg (132–187 lb) | 8'0"–9'0" | About 75–95 L |
| Over 85 kg (187 lb) | 9'0"+ | About 90–110 L |

Board Length and Volume by Type
One surf retailer's guide gives these ranges by board type and rider weight:
| Board Type | Rider Weight | Length | Volume |
|---|---|---|---|
| Longboard | Under 70 kg (154 lb) | 9'0"–9'2" | About 65–75 L |
| Longboard | 70–90 kg (154–198 lb) | 9'2"–9'6" | About 70–85 L |
| Longboard | Over 90 kg (198 lb) | 9'6"+ | About 80–100+ L |
| Mid-length | Under 65 kg (143 lb) | 6'8"–7'2" | About 40–48 L |
| Mid-length | 65–85 kg (143–187 lb) | 7'2"–7'10" | About 45–55 L |
| Mid-length | Over 85 kg (187 lb) | 7'10"–8'6" | About 52–65 L |
| Shortboard | Under 65 kg (143 lb) | 5'6"–5'10" | About 24–28 L |
| Shortboard | 65–80 kg (143–176 lb) | 5'10"–6'2" | About 27–34 L |
| Shortboard | Over 80 kg (176 lb) | 6'1"–6'6" | About 32–40 L |
Weight-to-Volume Ratios by Level
Surf Simply expresses board size as pounds of body weight per liter of volume, a useful way to see how volume drops as skill rises:
| Level | Body Weight per Liter |
|---|---|
| Level 1: learning in whitewater | About 2.0 lb/L (0.9 kg/L) |
| Level 2 | About 2.6 lb/L (1.2 kg/L) |
| Level 3 | About 3.0 lb/L (1.3 kg/L) |
| Level 3.5 | About 4.0 lb/L (1.8 kg/L) |
| Level 4 | About 6.0 lb/L (2.7 kg/L) |
| Level 4+ (professional) | About 6.6 lb/L (3.0 kg/L) |
Example: a 165-lb surfer at Surf Simply's level 2 ratio of 2.6 lb/L would look for about 63 liters. Surf Simply notes that around 3.5–4 lb/L is roughly the biggest board most people can duck dive.
Kids' Surfboard Sizes
| Age | Approx. Weight | Board Length |
|---|---|---|
| 4–6 | Under 29 kg (64 lb) | 4'0"–5'8" |
| 7–10 | 30–40 kg (66–88 lb) | 5'8"–6'2" |
| 11–13 | 40–50 kg (88–110 lb) | 6'2"–7'0" |
| 14+ | 50–59 kg (110–130 lb) | 7'0"–8'0" |
| 14+ | Over 59 kg (130 lb) | 9'0"+ |
Follows a surf retailer's kids' sizing guide; size by weight and ability rather than age alone. Soft-tops are safest for young kids.
Does Height Matter?
Weight and ability matter much more, because the board's volume has to float your mass. Height affects your stance width and balance, so taller surfers sometimes prefer a slightly longer board. A popular rule of thumb for intermediate longer boards is a board about a foot taller than you, but always check volume too.
Volume, Length, Width and Thickness
Boards are listed as length × width × thickness, for example 7'6" × 21½" × 2¾", often with volume in liters. Two boards of the same length can have very different volumes depending on width, thickness and outline. Width adds stability; thickness adds float but can make rails harder to sink in turns. When comparing boards, compare liters first.
Adjust for Board Type, Material and Waves
- Board type: fish and grovelers are short but wide, so they carry more volume for their length.
- Epoxy: EPS boards are more buoyant; some guides suggest about 2–3 liters less than a PU board.
- Waves: more volume helps in small, weak waves; less volume (and a step-up shape) helps in bigger, more powerful surf.
- Wetsuits: in cold water, a thick wetsuit adds weight and restricts movement, so a bit more volume helps.
- Duck diving: very high-volume boards can't be duck dived; you'll need to turtle roll.
Common Sizing Mistakes
- Buying a shortboard too early; it slows learning dramatically.
- Sizing by length alone without checking volume.
- Copying a pro surfer's board size.
- Ignoring fitness and how often you surf.

Frequently Asked Questions
What size surfboard should I get for my weight?
Use a chart that combines weight and ability. As a beginner, look for a high-volume board, often 8 to 9 feet or more for many adults. As you improve, you can ride shorter boards with less volume.
How many liters should my surfboard be?
Multiply your weight in kilograms by a factor for your ability (the Guild Factor). Advanced surfers often ride about 0.34–0.38 times their weight in liters; beginners need much more, with some guides suggesting close to 1 liter per kilogram.
What is the Guild Factor?
A multiplier that turns your body weight in kilograms into a suggested board volume in liters, based on your ability. Weight × Guild Factor = liters.
Does height matter when choosing a surfboard?
Weight and ability matter much more because volume has to float you. Height affects stance width and balance, and taller surfers may prefer slightly longer boards.
Should I start on a short board to learn faster?
No. Starting too small makes it harder to catch waves and stand up, which slows learning. Start big and move down gradually.
What size surfboard should a child use?
Small kids often ride boards around 4 to 6 feet, older kids around 6 to 7 feet and teens 7 feet or more, depending on weight. Soft-tops are best for young children.
Do epoxy boards need less volume?
Epoxy (EPS) boards are more buoyant, so some guides suggest about 2 to 3 liters less than a polyurethane board for the same rider.
How do I read surfboard dimensions?
Board size is listed as length x width x thickness, for example 7'6" x 21 1/2" x 2 3/4", often followed by the volume in liters.
