The short version: A threshold ramp solves a 1-3 inch trip hazard for under $80. Rubber for indoor, aluminum for outdoor. Buy the rise that matches your threshold exactly.

Why thresholds matter

Per ICC A117.1, thresholds in accessible homes should be 1/2 inch maximum.1 Most US homes have higher thresholds at exterior doors, sliding doors, and bathroom transitions.

For senior users, any 1/2-inch+ height change is a documented trip hazard. Threshold ramps are a $20-$80 fix that addresses one of the more common low-cost fall risks.

Sizing

Measure your threshold rise, the vertical distance the ramp needs to compensate. Buy a ramp with the same rise as your threshold.

If between sizes, go higher. A ramp that’s slightly taller than the threshold is safer than one that’s shorter.

Install

Place the ramp at the threshold. Confirm:

  • Door swings freely above the ramp.
  • Ramp doesn’t slide when stepped on.
  • Bottom edge meets floor flush, no gap.

Most threshold ramps don’t require permanent fastening for indoor use. For outdoor, screw to the deck or porch.
