Kayak Weight Capacity: How Much Room to Leave for Gear
A kayak's maximum capacity is the most it can float, not the load it paddles well with: Brooklyn Kayak Company's rule is "A basic rule of thumb is that a kayak will perform best if kept below 70% of its maximum weight capacity." Gear counts toward the load.
Three published rules
- The 70% rule (Brooklyn Kayak Company): capacity needed = load ÷ 0.7.
- The 25–50% rule (Kokopelli): pick "a weight limit that's 25-50% more than what you weigh". It counts body weight only.
- Usable capacity (Old Town): Old Town prints a usable figure under each total, for example the Loon 106 at 274 lb usable of 325 lb.
Worked examples
- 160 lb paddler with 25 lb of gear: load 185 lb; the 70% rule asks for 264 lb of rated capacity, Kokopelli 200–240 lb. 18 of 21 solo kayaks listed pass every rule; the shortest is the Ocean Kayak Malibu 9.5 (9 ft 5.04 in). See the 160 lb page.
- 200 lb paddler with 25 lb of gear: load 225 lb; the 70% rule asks for 321 lb of rated capacity, Kokopelli 250–300 lb. 11 of 21 solo kayaks listed pass every rule; the shortest is the Ocean Kayak Malibu 9.5 (9 ft 5.04 in). See the 200 lb page.
- 240 lb paddler with 25 lb of gear: load 265 lb; the 70% rule asks for 379 lb of rated capacity, Kokopelli 300–360 lb. 2 of 21 solo kayaks listed pass every rule; the shortest is the Sportsman 120 (12 ft). See the 240 lb page.
Why the rules disagree
The 70% rule and Old Town's usable figures land close together, because Old Town's usable capacity is about 85% of its total. Kokopelli's rule ignores gear, so it is the most forgiving for a loaded day trip and the strictest for a light paddler with nothing aboard. Paddleboards follow the same idea: iRocker says to stay 10 to 15% under a board's stated maximum, as the paddleboard pages show.

Questions
Can I use a kayak rated exactly for my weight?
It will float, but Brooklyn Kayak Company says a kayak performs best well under its maximum, and Old Town prints a lower usable capacity under each total.
Does gear count toward kayak capacity?
Yes. Old Town says to check that the maximum capacity covers your weight and any gear you bring.
