Our buying guides

How these pages are built

Every figure comes from the maker's product page, manual or the Amazon listing, and we only include models with a live, in-stock Amazon listing we checked ourselves. When sources disagree on a weight limit we use the lowest number. We do not test these machines ourselves.

Height fit starts from a typical walking step of 0.41 times your height (0.45 when walking briskly), adds 12 inches for your shoe, and 6 more inches of room to drift for a comfortable fit. These are rough guides, not measurements of you. Weight fit leaves 30 lb of headroom above your body weight.
