Grill Time Calculator

Grilling time and temperature depend on the protein, thickness, starting temperature, grill surface temperature, and desired doneness. Thickness is the dominant variable, and surface area matters far less than depth.

How time scales with thickness

Pure heat conduction to the center goes with the square of thickness, so on paper a 2-inch steak should take four times as long as a 1-inch one. Over the range people actually grill, roughly three quarters of an inch to two inches, it does not work out that way. You are flipping the meat, the grill is far hotter than the target temperature, and the surface is doing most of the work. Real grilling charts, including the one below, come out close to linear: double the thickness, roughly double the time per side. That is what this calculator uses.

The square law reasserts itself past about two inches, which is exactly why thick cuts get cooked by the reverse sear method described further down rather than straight over the coals.

Safe internal temperature reference (USDA guidelines):

Whole beef and lamb carry bacteria on the cut surface, which the grill sears off, so a rare center is a real option. Ground beef does not get that concession: grinding mixes the surface right through the patty, so the whole thing has to reach 160°F. Chicken has no rare setting at any thickness. The calculator will not let you choose one for those three, and says so when you try.

Typical grilling times at 450–500°F (high heat):

The rest period: Always rest meat after grilling. Resting allows internal temperature to equalize and juices to redistribute.

Rest Time ≈ Grill Time × 0.25 to 0.50

A steak grilled for 10 minutes should rest 2.5–5 minutes before cutting. Cutting immediately releases 30–40% more juice onto the plate.

Reverse sear method: For thick cuts (1.5"+), cook at 250°F indirect until 10°F below target temperature, then sear 90 seconds per side at maximum heat. This produces perfectly even doneness throughout the entire cut.
