Harness Sizing Guide
Enter your height and all-up flying weight to get a general size suggestion and see how your weight compares to that size's typical range.
Suggested harness size
Your all-up weight sits within the typical range for this size.
How this guide works
The guide places your height into one of five general bands (XS through XL) that roughly mirror how harness manufacturers typically size their models, then checks your all-up flying weight against a typical certified weight range for that size to flag whether it's worth checking a size up or down.
These are general, industry-typical bands built for orientation, not any single manufacturer's exact chart — brands vary in cut, back length, and certified weight ranges even within the same nominal size. Use this as a starting point before comparing the specific harness models you're considering.
Frequently Asked Questions
How is harness size usually determined?
Manufacturers publish size charts for each harness model, typically driven mainly by pilot height (which sets torso/back length and the position of the leg straps and hang point), with a certified weight range attached to each size for structural rating and reserve container volume.
Why does this tool also ask for my weight?
Height gets you into the right size band for fit, but weight matters separately: a harness is only certified up to a maximum all-up weight for reserve deployment and structural reasons, and being near the bottom of a size's range can also affect comfort and container volume for smaller pilots.
What does 'all-up flying weight' mean here?
It's you plus everything you wear and carry in flight — clothing, boots, helmet, instruments, radio, and the reserve itself — not just your body weight. This is the same figure used for wing loading and for a harness or reserve's certified weight range.
My result says I'm above or below the typical weight range — what should I do?
Treat it as a prompt to check the next size up or down against that specific manufacturer's own chart, not a final answer — this tool uses general, industry-typical bands, not any one brand's exact figures. Trying the harness on, and ideally getting a check flight, is the only way to confirm fit and comfort.
General guidance only, not a substitute for the specific harness manufacturer's own size chart or a certified instructor's advice. Always confirm fit by trying a harness on and, where possible, getting a check flight before buying or flying a new one.
