Who should pick which

Pick the Sunny SF-X7110 Smart Ultra Curved Manual Treadmill if

  • you weigh more than about 190 lb. It is rated for 330 lb against 220 lb, and we suggest 30 lb of headroom above your weight.
  • you are tall or walk briskly. Its 59-inch belt suits walkers up to about 9'6" at slow desk pace (8'4" with 6 inches of room to drift), and up to about 7'7" for brisk walking, against 7'1" at slow desk pace on the 47.24-inch belt.
  • you want something to hold for balance, for example at faster speeds or on incline.

Pick the WalkingPad P1 if

  • you will move it in and out of storage often. It weighs 62 lb against 157 lb.
  • storage space is tight. It folds (yes, folds in half (180°)); the other one does not fold its deck.
  • you want to change speed without bending down to a console.
  • budget matters most. It sits in the mid-range tier.

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.
