Whether you’re in it for the long haul or short haul, there’s no denying that flying is largely about the constant quest for comfort. One factor that’s sure to make or break your flight is how much space you have—the amount of legroom often decides whether or not you’re able to stretch, work on your laptop, or even eat with ease using the tray table.

Legroom inches have been gradually disappearing in recent years, prompting the development of new products intended to help protect our space and even the occasional in-flight legroom spat. But not all airlines are created equal when it comes to legroom, so we’ve pulled the numbers for major U.S. and Canadian airlines to help break it down for you.

To measure how much legroom a seat offers, the industry uses a term called the “seat pitch.” The seat pitch measures the distance from the headrest of one seat to the headrest behind it, offering an idea of how much room a passenger can expect. Because airlines are constantly updating their cabins and fleets, the figures listed below are subject to change. Still, this guide offers up a general idea of how much legroom to expect on your next flight.
