How to Size a Walking Cane Correctly

There's a good chance you already own the cane this post is about.

It's in the hall closet, or behind the bedroom door, tag still on it. Your mom used it twice - said it felt awkward, that it "hurt her wrist" or made her feel like she was hunched over it — and quietly set it aside. The family drew the obvious conclusion: she just isn't ready. She's being stubborn about it.

Maybe. But before you file it under resistance, check one thing almost nobody checks first: that cane was very likely the wrong size.

This is the part that surprises people. A cane that's mis-fitted doesn't feel neutral - it feels genuinely bad to walk with. It strains the wrist, tips the body forward, asks the shoulder to do work it shouldn't. So the person using it isn't wrong when they say it's uncomfortable. They're describing a real problem. Everyone just aims the blame at the wrong thing - at them, instead of at four inches of aluminum.

Here's why it matters more than "comfort," though: a badly sized cane is worse than no cane at all. It feels like support, so the person trusts their weight to it - and it isn't quite there when they reach for it. That's the exact moment a cane is supposed to prevent.

The good news is that getting it right takes about thirty seconds and no special tools. And the same closet cane, re-fitted, is often the one that finally gets used. Here's how.

Mistake #1: the height

There's a lot of guesswork out there - "about hip height," "roughly half your height." Skip all of it. There's one reliable method, and physical therapists use it because it works on every body regardless of proportions.

The wrist-crease method:

1. Put on the shoes your parent actually wears every day. Not barefoot, not slippers - the real shoes, because shoe height changes everything.
2. Have them stand up straight, as tall as is comfortable, arms hanging relaxed at their sides. Not reaching, not holding anything.
3. Look at the crease of the wrist - the line where the hand meets the arm.
4. The top of the cane handle should sit right at that wrist crease.

That's it. When the cane is the right height, the hand falls naturally onto the handle without lifting the shoulder or dropping it.

The elbow check. Here's the confirmation: when they hold a correctly-sized cane and stand normally, their elbow should be bent at a comfortable, slight angle - roughly 15 to 20 degrees. Not a straight, locked arm (cane too tall). Not a sharp bend (cane too short). A little give in the elbow is what lets the arm absorb weight and push off. If the arm is ramrod straight or folded up tight, the height is off.

What "too tall" and "too short" actually cause:

• Too tall - the shoulder hikes up, the wrist bends awkwardly, and the cane can't take real weight. Over time: shoulder and wrist strain, and a cane that quietly stops being used. (This is our closet cane, more often than not.)
• Too short - the body leans forward and down to reach it. That pushes the center of gravity forward, encourages a hunch, and makes tripping more likely, not less.

Both feel a bit wrong from day one. So when your parent says the cane is "uncomfortable" or "awkward," take it literally before you take it personally — check the height first. Very often that one word is the whole story, and the fix is a thirty-second adjustment, not a longer conversation about whether they're ready.

Mistake #2: the wrong hand (this one surprises everyone)

Ask most people which hand a cane goes in, and they'll say the same side as the bad leg. It seems obvious - support the weak side, right?

It's backwards. The cane goes in the hand opposite the weaker or more painful leg.

If the right knee or hip is the problem, the cane goes in the left hand. Here's why, and it's worth understanding rather than just memorizing:

• It widens the base of support. A cane on the same side just props up a body that's already listing that way. On the opposite side, it braces you across your center - far more stable.
• It takes load off the sore leg. When you step onto the painful right leg, you press down through the cane in your left hand at the same moment. The cane and the weak leg share the load, the way a healthy opposite leg normally would.
• It matches how we naturally walk. In a normal stride, the opposite arm and leg swing together - left arm forward with right leg. Holding the cane on the opposite side keeps that natural rhythm instead of fighting it.

The movement, put simply: the cane moves forward at the same time as the sore leg. Cane and sore leg step together; strong leg steps on its own. "Cane and the sore leg, together" is the whole thing to remember.

Picture our closet cane again. If it was in the wrong hand, every step quietly fought the body's natural rhythm - which also feels awkward, and also gets called stubbornness. Two small mistakes, one unfair verdict.

(If the weakness is even on both sides, or it's a balance issue rather than one sore leg, most people go with their dominant hand - but this is exactly the kind of thing a physical therapist can confirm in five minutes for a specific situation.)

The measurement most people skip: the tip

Getting the height right is worthless if the bottom of the cane can't grip.

The rubber tip is the cane's contact with the floor - its tread, like a tire. And like a tire, it wears down, goes smooth and hard, and starts to slip, especially on the surfaces that matter most: wet tile, a polished floor, a smooth entryway. A worn tip on a perfectly-sized cane undoes all the fitting work you just did.

Check it in ten seconds: turn the cane over and look at the bottom. If the tread is worn flat, the rubber has gone hard and shiny, or the edges are cracked, replace it. Tips are a few dollars and push on by hand. It's the cheapest, most-ignored safety upgrade there is

Adjustable canes make this easy - if you actually adjust them

A fixed-height cane has to be cut to size or it's simply wrong - and if it came pre-cut for someone else, that's your closet cane right there. An adjustable cane solves that: you set the exact height, re-check it as shoes or needs change, and one cane fits whoever's using it.

But the adjustment only helps if someone does it properly. Two things people get wrong:

• They leave it at the factory setting - often the tallest one, straight out of the box. Always set it to the wrist crease before the first real use.
• They don't lock it fully. Whatever the mechanism — a push-button that clicks into a hole, a twist collar, a locking screw — make sure it's fully engaged and the cane doesn't telescope or wobble when weight goes on it. Give it a firm press straight down before trusting it.

The 30-second fitting, start to finish

Next time you're with your parent, do this:

1. Everyday shoes on. Stand up straight, arms loose at the sides.
2. Handle to the wrist crease. Adjust (or plan to buy) so the top of the handle meets the wrist.
3. Check the elbow — a slight, comfortable bend, not locked, not sharp.
4. Right hand for it: opposite the sore leg.
5. Flip it over and check the tip has real tread left.

That's a properly fitted cane — one that actually supports weight, matches how they walk, and grips the floor.

And here's the quiet payoff. Go dig the closet cane out. Put the everyday shoes on, drop the handle to the wrist crease, move it to the opposite hand, check the tip. Very often the thing your parent called "uncomfortable" a month ago stops feeling that way — because it was uncomfortable, and now it isn't. The cane that read as resistance turns out to have been a fitting problem the whole time. That's the difference between a cane that lives in the closet and one that comes out the door with them.

If your parent is recovering from surgery, has a specific condition, or uses the cane on both sides, a physical therapist can confirm the fit and the walking pattern in a single short visit. This is general fit guidance, not a substitute for that.
