High-altitude bread calculator

Yeast bread rises faster at altitude. Enter your elevation — but the bigger fix for bread is timing, not just ingredients.

In short

At altitude, dough rises roughly 25% faster, so the key move is to punch down after the first rise and do a second rise rather than over-proofing. Add a little liquid for the dry air, and reduce yeast slightly.

Starting points, not a formula

High-altitude baking is trial-and-error. These adjustments come from Colorado State University Extension guidance — the standard reference — but the right change depends on your exact elevation, oven, and recipe. Change one thing at a time and take notes.

How does altitude affect bread?
Lower pressure makes dough rise faster, so it can over-proof. Punch it down and do a second rise, watch it rather than the clock, and add a touch more liquid.
Do I reduce yeast at high altitude?
A small reduction helps slow the over-fast rise, but the bigger lever is timing — don't let a single rise run too long.
