Underarm Crutches for Tall People: The Only Fit Past 6 Feet 8

If you are very tall and need crutches, the underarm style is where the answer lives. This guide gives you the numbers and the fit rules.

The range nobody else reaches

Most retail underarm crutches, including the “tall adult” tier, stop fitting somewhere around 6’6”. The In-Motion Pro Underarm Crutch (Tall), SKU 6500, was built for the users the rest of the market rounds away:

Fits users from 5’10” to 7’1”, on the published spec sheet, not a marketing estimate
Floor-to-cradle: 48” to 62” across 15 positions, so the fit lands exactly
Handle adjusts independently, 16” to 20.5” below the cradle in 4 positions
350 lb capacity, with the structural margin a bigger frame deserves
Spring Assist Technology, Millennial Medical’s shock-absorbing post design, built to reduce walking impact by up to 40% compared to a rigid post
Articulating tips that stay flat through a long stride on pavement, grass, gravel, and indoor floors

At 6’9” and above this stops being a comparison and becomes the answer: off-the-shelf forearm crutches end at 6’8”, so the underarm Tall is the one crutch that fits without a custom build.

Underarm fit is two numbers, not one

A properly fitted underarm crutch touches your body in two places, and both have a rule:

The cradle sits 1 to 1.5 inches below your armpit while you stand upright. It should never carry your body weight; it stabilizes against your ribcage while your hands do the work.
The handle lands at your wrist crease with your arm relaxed, leaving a slight elbow bend when you grip.

Tall users get burned by crutches that adjust only overall length: the cradle ends up right, and the handle ends up wrong, or the reverse. That is why the In-Motion underarm models adjust the handle separately from the cradle. Both contact points land where they should, whatever your proportions.

To find your numbers, measure floor to wrist crease standing straight in your everyday shoes, and check it against the published range. The full walkthrough is in our sizing guide.

When forearm is still the better call

Honesty matters more than the sale: if you are between 5’10” and 6’8” and expect to be on crutches for months rather than weeks, the In-Motion Tall forearm crutch deserves a look: arms swing more naturally, and the cuffs free your hands. The full comparison is in forearm vs underarm for tall people. Above 6’8”, the decision makes itself.

Whichever style you land on, have your clinician or physical therapist confirm the final fit, especially for long-term use.

Frequently asked questions

What is the tallest underarm crutch you can buy?

The In-Motion Pro Underarm Crutch (Tall) from Millennial Medical fits users from 5 feet 10 to 7 feet 1, with a floor-to-cradle range of 48 to 62 inches across 15 positions. We are not aware of a taller off-the-shelf crutch in any style.

Are underarm crutches good for tall people?

Yes, when the crutch actually reaches. A tall-specific underarm model with an independently adjustable handle fits tall proportions properly: cradle 1 to 1.5 inches below the armpit, handle at the wrist crease, elbow slightly bent. The problem is standard sizing, not the style.

Should you rest your weight on the underarm cradle?

No. Your hands carry the load; the cradle stabilizes against your ribs. Resting body weight on the armpit is uncomfortable and is exactly what a proper handle-height fit prevents. Have your clinician or physical therapist confirm your setup.

I am 7 feet tall. Do any crutches fit me?

Yes, one: the In-Motion Tall underarm crutch fits users to 7 feet 1. Past that height you are into custom fabrication, and a clinician or orthotics provider is the right next call.
