One profile, every answer, every source
Gear Fit Atlas reads the brands' own published size charts — evo, K2 and Faction for skis; Jones, evo, Never Summer and Burton for snowboards; Old Town and Pelican spec sheets for kayaks; iRocker, Alpkit, Red Paddle Co and ISLE for paddleboards; Specialized, Santa Cruz and Norco for bikes; Osprey, Gregory and Gossamer Gear for packs — and puts them side by side.

How the answers are worked out
Skis and snowboards are read straight off the brand charts. When your height or weight falls between two printed rows, both rows are read and the answer spans them; nothing is interpolated. Where several charts cover you, the tool shows the span across all of them and, when they share one, the window every chart agrees on.
Kayaks are checked against three published capacity rules: Brooklyn Kayak Company's 70% performance rule, Kokopelli's rule of a limit 25 to 50% over body weight, and Old Town's own usable capacity. Paddleboards use iRocker's and Alpkit's volume rules and iRocker's length and width chart. Bikes read each model chart's rider-height span; packs read each brand's trip-length guidance by nights.
The methodology lists every source, the date it was read and what was left out — Trek and Perception among them, because their charts could not be read from the brand.
