Looking for rubber caps for chair legs? The secret most people don't know: the heavy-duty rubber tips sold for canes and crutches are the exact same product — thick-walled rubber cups sized by inside diameter — and they outlast the thin "chair leg caps" sold in big-box stores by years.
How to Measure Your Chair Legs
Measure the outside diameter of the chair leg tube (or the width of a square leg). That measurement is the inside diameter (ID) of the cap you need. Common sizes:
| Chair leg diameter | Cap to order |
|---|---|
| 3/8" (light café chairs, wire furniture) | 3/8" ID rubber tips |
| 3/4" (standard folding chairs) | 3/4" ID rubber tips |
| 7/8" (metal stacking chairs) | 7/8" ID rubber tips |
| 1" (heavy stools, shop chairs) | 1" ID rubber tips |
| 1" square legs | 1" square rubber caps |
| 1-1/8" – 1-1/4" (bar stools, walkers) | 1-1/8" and 1-1/4" ID tips |
Between sizes? Rubber stretches — pick the size at or just under your leg diameter for a snug fit that won't fall off.
Round vs Square Legs
Round tube legs take standard cup-style tips. Square legs need square rubber caps — forcing a round cap on a square leg splits the rubber at the corners.
Why These Beat Big-Box Chair Caps
Hardware-store chair caps are thin-walled and split within months on chairs that get dragged. Our tips are the medical-grade thick-wall style built for canes bearing full body weight — on a chair they last for years, grip hard floors, and never mark tile or hardwood.
