Sizing Guide

The right fit is the difference between a product that helps and one that sits in the closet. These instructions cover the measurements you need before ordering. If you are between sizes or unsure, email [support@yourdomain.com] with the user's height, weight, and the product you are considering, and we will help you choose.

Before you measure

  • Measure while standing, wearing the shoes the person normally wears.
  • Stand as upright as comfortable, with shoulders relaxed and arms hanging at the sides.
  • Use a tape measure or a ruler against a wall. A second person makes this easier and safer.
  • If the user cannot stand safely, do not measure standing. Ask a clinician or therapist to size the aid.
  • Have someone nearby who can assist during the measurement.

Canes and walking sticks

What to measure: the distance from the floor to the wrist crease of the hand that will hold the cane.

  1. Stand upright in normal shoes with arms relaxed at your sides.
  2. Find the crease on the inside of your wrist, where the hand bends.
  3. Measure from the floor straight up to that crease.
  4. Choose a cane whose handle height adjusts to that measurement.

Check the fit: with the cane tip on the floor and your hand on the handle, your elbow should bend about 15 to 30 degrees. Your shoulders should stay level. If you have to lean or shrug, adjust the height.

Tip: hold the cane in the hand opposite the side that needs support. If both sides need support, talk to a clinician before choosing a single-point cane.

Forearm crutches

What to measure: your height, the distance from the floor to your wrist crease, and the circumference of your forearm at its widest point below the elbow.

  1. Stand upright in normal shoes with arms relaxed.
  2. Measure from the floor to the wrist crease.
  3. Measure around your forearm about 1 to 1.5 inches below the elbow crease.
  4. Choose a crutch whose grip height and cuff size fit those numbers.

Check the fit: the forearm cuff should sit about 1 to 1.5 inches below the elbow crease, with the cuff loose enough to slide on and off but snug enough to stay in place. With your hand on the grip, your elbow should bend about 15 to 30 degrees.

Note: some models are made for the left or right arm. Check the product page before ordering.

Shower chairs and stools

What to measure: the distance from the shower floor to the back of your knee, and the width of the shower or tub area.

  1. Sit on a firm chair with your feet flat on the floor and your knees bent about 90 degrees.
  2. Measure from the floor to the crease behind your knee.
  3. Choose a seat height close to that measurement. A seat that is too low is hard to stand up from; one that is too high leaves your feet dangling.
  4. Measure the shower or tub floor area, including the door opening, and compare it with the chair's outside dimensions.
  5. Confirm the chair fits inside the shower or tub and that the door or curtain still closes.

Check the fit: seated with feet flat, your knees should be at about 90 degrees and your thighs supported by the seat. The chair should sit flat and stable, with all four feet on the floor.

Commode chairs and bedside commodes

What to measure: the distance from the floor to the back of your knee, your hip width, and, for a commode used over an existing toilet, the height and width of the toilet.

  1. Measure floor to the crease behind your knee, as for a shower chair.
  2. Measure the widest part of your hips and add a few inches for comfort and clothing.
  3. If the commode will sit over a toilet, measure the toilet seat height and the space around the base.
  4. Check the product's seat height, seat width, weight capacity, and bucket capacity.

Check the fit: seated, your feet should be flat and your knees at or slightly below hip level. The frame should not wobble. If the commode has arms, you should be able to stand up using them without the frame tipping.

Weight capacity

Products with a confirmed rating show it on the product page and in the Fit and compatibility section. Where a rating is not yet published, contact us before ordering and we will confirm it for that model. A rating is a limit, not a target: choose a product rated above the user's weight, especially if the user has difficulty controlling their movements or transfers weight suddenly. Do not use a product rated below the user's weight, even briefly.

Still not sure?

Email [support@yourdomain.com] or call [Phone], Monday through Friday, 9:00 a.m. to 5:00 p.m. Eastern Time. Tell us the user's height, weight, and where the product will be used, and we will recommend a size or model. We can help with product specifications, but we cannot give medical advice. For clinical fitting, ask your physician or physical therapist.
