To measure for a cane, stand upright in your normal walking shoes with your arms relaxed at your sides. Have someone measure the distance from the floor to the crease of your wrist, where your hand meets your forearm. That measurement is your ideal cane length. When you grip a cane at that height, your elbow will bend about 15 to 20 degrees, which is the sweet spot for comfortable weight bearing.
The Wrist Crease Method
This is the most reliable way to size a cane at home, and it’s the same approach physical therapists use. Here’s how to do it step by step:
- Put on your everyday shoes. Heel height changes the measurement by 1 to 2 inches, so wear the shoes you’ll actually walk in most often.
- Stand up straight on a flat surface. Look ahead, not down. Let your arms hang naturally at your sides.
- Find your wrist crease. This is the horizontal line where the palm side of your hand meets your forearm. It’s easy to spot if you flex your wrist slightly, then relax it.
- Have someone measure from the floor to that crease. Use a tape measure and keep it vertical. That number, in inches, is your cane height.
A study testing this method on 52 volunteers found that 94% of people ended up with the recommended 20 to 30 degrees of elbow bend when sized this way. The alternative approach, which involves measuring half of a person’s standing height, only worked for about 8% of people, producing an elbow angle that was far too steep for comfortable use. The wrist crease method is clearly the better option.
Why Elbow Angle Matters
A cane that’s the right height lets you transfer weight through your arm efficiently without straining your shoulder or wrist. The target is 15 to 30 degrees of elbow bend. That’s a slight, comfortable flex, not a straight arm and not a sharp angle. If you’re using a cane primarily for balance rather than to take weight off a painful leg, you can go toward the higher end of that bend range.
A cane that’s too tall forces your shoulder up and your elbow out at an awkward angle, which can cause neck and shoulder soreness over time. A cane that’s too short makes you lean to one side, stressing your lower back and putting uneven pressure on your spine. If you’re experiencing pain in your shoulder, wrist, or back while using a cane, the height is likely off.
Quick Reference by Height
If you want a ballpark before measuring, these general ranges work as a starting point:
- Under 5’4″: approximately 34 inches
- 5’4″ to 6’0″: approximately 37 inches (this is the standard cane length sold in most stores)
- Over 6’0″: approximately 40 inches
These are rough guidelines. Arm length varies a lot between people of the same height, so the wrist crease measurement is always more accurate. Use the chart to confirm your number is in the right neighborhood, not as a substitute for actually measuring.
How to Verify the Fit
Once you have a cane in hand, there’s a simple check. Stand in your walking shoes, grip the cane handle, and place the tip about 6 inches to the side of your foot. Look at your elbow. If it’s bent at a gentle, comfortable angle (roughly 15 to 20 degrees), the cane fits. If your arm is nearly straight, the cane is too tall. If your elbow is bent sharply or your shoulder is hiking up, something is wrong with the length.
Have someone take a photo from the side while you hold the cane naturally. It’s much easier to spot problems from a photo than by looking down at your own arm.
Adjustable vs. Fixed-Height Canes
Adjustable canes have a push-button or twist-lock mechanism that lets you change the height in small increments, usually half an inch at a time. These are a good choice if you’re a first-time cane user, recovering from surgery (since your posture and gait may change as you heal), or if you switch between shoes with different heel heights. Once you dial in the right setting, make sure the locking mechanism clicks firmly into place before putting weight on it.
Fixed-height canes, especially wooden ones, need to be cut to size. To shorten a wooden cane, turn it upside down and place the handle on the floor. Have someone mark the shaft right at your wrist crease. Remove the rubber tip by twisting it off, cut the cane at the mark, and replace the tip. If you don’t have the right saw at home, most hardware stores will make the cut for you, often for free. Always remeasure before cutting, because you can’t add length back.
When to Remeasure
Your cane height isn’t necessarily a one-time measurement. You should recheck the fit if you change your regular footwear, especially going from flat shoes to something with a heel or vice versa. Post-surgical recovery is another common reason: as swelling decreases and you regain a more upright posture, the cane length that worked in week two may be too short by week eight. Any change in posture, whether from a new condition or simply from feeling stronger, is worth a quick remeasurement.
Measuring When Someone Can’t Stand
If you’re sizing a cane for someone who can’t stand upright, such as a person recovering in bed, the wrist crease method won’t work directly. In clinical settings, height can be estimated from other body measurements that don’t require standing. Knee height (measured with a caliper from the sole of the foot to the top of the knee while sitting), forearm length, or the distance from the center of the chest to the tip of the middle finger can all be plugged into standard formulas to estimate standing height. From there, you can use the height-based reference ranges as a starting point and fine-tune the cane once the person is able to stand and walk.
For a practical at-home workaround, have the person sit at the edge of a bed or chair with their feet flat on the floor in their walking shoes. Measure from the floor to the wrist crease the same way you would while standing. This won’t be as precise as a standing measurement, but it gets you close enough to choose an adjustable cane and refine the setting later.
