High-Altitude Baking Adjuster
Enter your elevation. Above about 3,000 ft (900 m) you get the common high-altitude pattern: a little more liquid, a little less leavening and a hotter oven. It is a rule of thumb, not a rewritten recipe.
Frequently asked questions
Is this exact for my recipe?
No. It is a rule of thumb from common high-altitude baking guidance: more liquid, less leavening, a hotter oven. Cakes, breads and cookies do not all respond the same way, so test and adjust.
Why does altitude change baking?
Air pressure is lower, so water boils at a lower temperature, liquids evaporate faster and gases expand more. Batters rise fast and then collapse or dry out.
Do I change anything below 3,000 ft?
Usually not. Most sea-level recipes work as written below about 3,000 ft (900 m).
