A properly sized cane should reach the crease of your wrist when you stand upright with your arm hanging naturally at your side. This single measurement is the most reliable way to get the right fit, and it typically works out to roughly half your height. Getting it wrong by even an inch can turn a helpful mobility aid into a source of shoulder pain, poor posture, or instability.
The Wrist Crease Method
Stand up straight in the shoes you normally walk in. Let your arms hang relaxed at your sides. Have someone measure the distance from the floor to the crease on the inside of your wrist, where your hand meets your forearm. That measurement is your ideal cane length.
This method was validated in a study published in the Journal of Rehabilitation Research and Development, which compared two common sizing techniques and concluded that measuring from the floor to the distal wrist crease produces the best result. It’s the same approach recommended by the Mayo Clinic and Cleveland Clinic.
When you grip the cane at the correct height, your elbow will bend slightly. That small bend is important. A straight, locked elbow means the cane is too tall. A deeply bent elbow means it’s too short. The slight flex lets you push off efficiently with each step while keeping your shoulder relaxed.
Why Footwear Matters
Always measure while wearing the shoes you plan to walk in most often. A half-inch difference in sole or heel height changes where the cane handle sits relative to your wrist. If you switch between sneakers and dress shoes regularly, size for whichever pair you wear for longer walks or more demanding activity. Some people with very different footwear heights find it worth having an adjustable cane they can tweak by a notch depending on the day.
How to Check the Fit
Once you have a cane at the right length, do a quick standing check. Place the tip about 2 inches in front of your foot and 6 inches to the side. In this position, two things should be true: the handle should sit level with the crease of your wrist, and your elbow should have a comfortable, slight bend when you grip it. If you have to hike your shoulder up or lean to one side, the height is off.
You can also do a walking check. Take a few steps on a flat surface. The cane should feel like a natural extension of your arm, not something you’re reaching down for or propping yourself up against. If your opposite shoulder starts dipping or you feel strain in your hand or forearm after a minute of walking, re-measure.
What Happens When the Size Is Wrong
A cane that’s too short forces you to lean forward. Over time, this puts extra stress on your lower back and shifts your center of gravity in a way that actually increases fall risk. Your wrist and hand also absorb more impact than they should because you’re pressing down at an awkward angle.
A cane that’s too tall pushes your shoulder upward with every step. This leads to tension in the neck, shoulder, and upper back. It also reduces how much weight the cane can realistically support, because your arm can’t generate force efficiently when your elbow is barely bent or fully extended. People with a too-tall cane often compensate by gripping harder, which causes hand fatigue and can aggravate conditions like arthritis.
Adjustable vs. Fixed-Length Canes
Most canes sold in pharmacies and medical supply stores are adjustable. They use a push-button mechanism: a spring-loaded pin that clicks into one of several holes along the shaft. To change the height, press the button in, slide the lower section to the desired hole, and release. The pin should pop fully through the hole before you put any weight on it. If your cane also has a twist collar near the adjustment point, tighten it after setting the height for extra security.
Check the pin before every use. If it doesn’t protrude completely through the hole, the cane can collapse under load. This is the most common safety issue with adjustable canes and the one most often overlooked.
Fixed-length wooden canes can be cut to size with a saw. Measure carefully and cut from the bottom, then add a new rubber tip. Once cut, there’s no going back, so it’s better to remove a little at a time and recheck the fit rather than taking off too much at once.
Which Side to Hold the Cane
Hold the cane on your stronger or uninjured side, not the side that hurts. This feels counterintuitive, but it works because of how your body shifts weight during walking. When you step forward with your weaker leg, the cane on the opposite side creates a wider base of support and reduces the load on the painful joint. If you’ve been told otherwise by a physical therapist for a specific condition, follow their guidance, but the opposite-side rule applies to the vast majority of cane users.
Rubber Tips and Traction
Every cane should have a nonskid rubber tip. Tips wear down over time, and a smooth, worn tip on a tile or wet floor is a fall waiting to happen. Check the bottom of your cane tip monthly. If the tread pattern has worn flat or the rubber has cracked, replace it. Replacement tips are inexpensive and available at most pharmacies. They come in standard sizes, so bring your cane or measure the shaft diameter before buying.
