A half sheet pan is 13 inches wide, 18 inches long and 1 inch deep. Half sheet pans are useful for many kitchen tasks, including baking and roasting.
Half sheet pans are ideal for baking cookies. Due to the rimmed edges, a half sheet pan also works well for roasting vegetables, roasting meats and making granola, as everything stays inside the pan. Half sheet pans are sturdy and do not buckle; when placed under cake and bread pans, they protect the oven floor from spilled batter.
Pre-cut sheets of parchment fit perfectly in half sheet pans, as they are a standard size. Eighth, quarter, three-quarter and full sheet pans are also available.
