Who should pick which

Pick the Horizon 7.4 AT if

you are tall or walk briskly. Its 60-inch belt suits walkers up to about 9'9" at slow desk pace (8'6" with 6 inches of room to drift), and up to about 7'9" for brisk walking, against 5'11" at slow desk pace on the 41.3-inch belt.
you drift sideways while you read or type. A 22-inch belt gives more room than 16.5 inches.
storage space is tight. It folds (Yes); the other one does not fold its deck.
you also want to jog or run. It reaches 12 mph against 4 mph.
you want something to hold for balance, for example at faster speeds or on incline.

Pick the Merach UltraWalk W60 (Plus) if

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.
