Paddle Board Size Chart: Pick the Right SUP by Weight

The paddle board size chart

A paddle board is a fit for the rider, not just a length: it should be long enough to glide and wide enough to stand on, and it should float high enough that the deck stays dry. Too short and the board is slow and tippy, which is how beginners fall in. Too long and the board is heavy, hard to carry, and hard to turn. The rule is simple: the height band decides the row, and the weight band is the check — a rider at 5 ft 8 in takes the 10 ft 6 in–11 ft board, not the 12 ft board, because the shorter board is the smallest board that fits.

The sizes are the standard boards the shops sell: 9 ft 6 in to 14 ft long, 30 in to 34 in wide, and 140 L to 320 L of volume. The volume is the float: a board with more litres sits higher in the water and carries more weight, and a board with fewer litres sits lower and turns faster. The width is the balance: a wider board is steadier to stand on, and a narrower board is faster to paddle. The length is the glide: a longer board tracks straighter and glides further per stroke, and a shorter board turns faster.

How to read the chart

The sizing rule is height first, weight as the check. Find your height band, then read the board. If your weight is inside the weight band for that row, the board fits. If your weight is heavier than the row your height suggests, size up one board: a rider at 5 ft 8 in and 200 lb is row 3 by height, but 200 lb is above the row’s 150–180 lb band, so they size up to the row 4 board, 11 ft–11 ft 6 in. If your weight is over 280 lb, take the biggest board, 12 ft 6 in–14 ft, whatever your height.

The worked example, line by line

Setup: a rider 5 ft 8 in tall, weighing 170 lb; find the board size.

Line 1 — the height band. 5 ft 8 in is in the 5 ft 5 in–5 ft 8 in band, which is row 3.

Line 2 — the board. Row 3 is a 10 ft 6 in–11 ft board, 32 in wide, with 190–210 L of volume.

Line 3 — the weight check. 170 lb is inside the row’s 150–180 lb band, so there is no size-up: the row 3 board fits as it is.

Line 4 — the reverse. An 11-ft board suits 5 ft 0 in–6 ft 0 in riders (rows 2–4), so a board you already own at 11 ft fits a wide range of riders.

Every branch, checked

5 ft 4 in / 140 lb: 5 ft 4 in is in the 5 ft 0 in–5 ft 4 in band, which is row 2: a 10 ft–11 ft board, 31 in wide, 170–190 L. The weight, 140 lb, is inside the row’s 120–150 lb band, so there is no size-up.

6 ft 1 in / 220 lb: 6 ft 1 in is in the 6 ft 1 in–6 ft 4 in band, which is row 5: an 11 ft 6 in–12 ft board, 33 in wide, 230–260 L. The weight, 220 lb, is inside the row’s 210–240 lb band, so there is no size-up.

4 ft 10 in / 110 lb: 4 ft 10 in is under 5 ft 0 in, which is row 1: a 9 ft 6 in–10 ft 6 in board, 30 in wide, 140–170 L. The weight, 110 lb, is under the row’s 120 lb top, so there is no size-up.

6 ft 5 in / 260 lb: 6 ft 5 in is over 6 ft 4 in, which is row 6: a 12 ft–12 ft 6 in board, 34 in wide, 260–290 L. The weight, 260 lb, is inside the row’s 240–280 lb band, so there is no size-up.

5 ft 8 in / 200 lb: 5 ft 8 in is row 3 by height, but 200 lb is above the row’s 150–180 lb band, so the rider should size up one board to the row 4 board, 11 ft–11 ft 6 in. A board that is too small for your weight sits low and tips — and a board one size up is steadier, even if it is a little slower to turn.

Reverse — the 11-ft board: an 11-ft board suits 5 ft 0 in–6 ft 0 in riders (rows 2–4), because 11 ft is inside the length range of rows 2, 3 and 4. A 9 ft 6 in board suits under 5 ft 0 in riders (row 1) only, because 9 ft 6 in is inside the length range of row 1 alone. If you already own the board, the reverse tells you who it fits; if you are buying, the forward lookup tells you what to buy.

What the defaults assume

This chart is a paddle board size chart only: it is NOT a paddle-length chart — it does not say which paddle length fits a rider, which depends on the paddler and the board — and it is NOT a weight-capacity chart — it does not say how much weight a board holds, which depends on the board and the maker. It assumes a flat-water all-round board: a racing board is longer and narrower for the same rider, and a surfing board is shorter and wider. It assumes the rider stands on flat water: a rider on choppy water needs a wider board than the chart says, and a rider carrying gear needs more volume than the chart says. Rounding convention: all lengths are in feet and inches, all volumes in litres, and all figures are taken from the chart row as written.

Who uses this

• The first-time buyer at 5 ft 8 in and 170 lb: they learn they need a 10 ft 6 in–11 ft board, 32 in wide, 190–210 L — and a 9 ft 6 in board is too small, so it would sit low and tip.
• The taller rider at 6 ft 1 in and 220 lb: they learn they need an 11 ft 6 in–12 ft board, 33 in wide, 230–260 L — and a 10 ft board is too short, so it would be slow and hard to stand on.
• The parent buying for a child under 5 ft: they learn a child under 5 ft needs a 9 ft 6 in–10 ft 6 in board, 30 in wide, 140–170 L — and an adult board is too big, so it is heavy and hard to carry to the water.
• The owner who already has an 11-ft board: they learn an 11-ft board suits 5 ft 0 in–6 ft 0 in riders (rows 2–4) — so they know who can borrow it, and whether the board they own fits the rider they are.

Accuracy & limitations

The lookup is exact for the numbers you enter: the board comes from the height band, and the weight band is the check. What the chart cannot do is know your water: a rider on choppy water needs a wider board than the chart says, and a rider carrying gear needs more volume than the chart says. If the weight band is heavier than the height band suggests, size up one board — a board that is too small for your weight sits low and tips, and a board one size up is steadier. It is explicitly NOT a paddle-length chart — the paddle length depends on the paddler and the board — and NOT a weight-capacity chart — how much weight a board holds depends on the board and the maker. It assumes a flat-water all-round board. For the same idea on the water, see kayak size chart; for the same idea on snow, see ski snowboard size chart.
