Quarter sheet pan, 13 by 9.5 inches
Quick answer
A quarter sheet pan measures 13 by 9.5 inches, which is 123.5 square inches of surface. It fits a standard domestic oven. For one or two portions, toasting nuts, and small toaster ovens.
These are the commercial sheet pan sizes, which are standardised across the industry.

How big is a quarter sheet pan?
13 by 9.5 inches, giving 123.5 square inches of surface. For one or two portions, toasting nuts, and small toaster ovens.
These sizes are standardised across the commercial baking industry, which is why a recipe that calls for a half sheet means a specific thing rather than an approximate one. The naming works by division: a full sheet is the base unit, a half sheet is half of it, a quarter sheet half again.
Which sheet pan actually fits a home oven?
Domestic ovens are usually about 22 to 24 inches wide inside, and a full sheet at 26 inches simply will not go in. Half sheet is the largest size that reliably fits.
This is the single most common sheet pan buying mistake. A full sheet is a commercial pan for a commercial oven, and it will not go in. The half sheet at 18 by 13 inches is the largest size that reliably fits a domestic oven, and it is the size nearly every home recipe means when it says "sheet pan". Two of them fit most ovens on separate shelves.
Why bare aluminium and not nonstick
Aluminium conducts at about 237 W/m-K, roughly fifteen times better than stainless at 16. That is why commercial sheet pans are bare aluminium: nothing else browns as evenly for the price. A dark nonstick coating absorbs more radiant heat and browns bases faster than the recipe expects, which is why baking instructions often tell you to reduce the temperature for dark pans.
Bare aluminium also discolours and develops a patina with use. That is cosmetic and does not affect performance, and it is the reason professional sheet pans look the way they do.

Common questions
What are the dimensions of a quarter sheet pan?
13 by 9.5 inches, which is 123.5 square inches of surface. These are standardised commercial sizes, so the figure is consistent across manufacturers. Rim height varies slightly between brands, usually around one inch, and it is the one dimension that is not standardised.
Will a full sheet pan fit in my oven?
Almost certainly not. A full sheet is 26 by 18 inches and domestic ovens are usually only 22 to 24 inches wide inside. It is a commercial pan for a commercial oven. The half sheet at 18 by 13 is the largest size that reliably fits a home oven and is what home recipes mean.
How many sheet pans should I own?
Two half sheets, at minimum. The limiting factor when roasting is oven shelf space rather than anything else, and one pan means cooking in sequence while the first batch goes cold. A wire rack that fits inside one is the highest-value addition after the second pan, because it puts air under the food instead of a wet surface.
Should I buy nonstick sheet pans?
Generally no. Bare aluminium browns more evenly, costs less and lasts indefinitely, while a nonstick coating on a sheet pan wears out under metal spatulas and high oven heat. Parchment paper solves sticking completely and costs almost nothing. Dark coated pans also brown bases faster than recipes assume.
What is a jelly roll pan?
A jelly roll pan is 15.5 by 10.5 inches, slightly smaller than a half sheet at 18 by 13. The two are frequently sold interchangeably, which matters if you are buying a wire rack to fit inside one. Measure before you buy accessories rather than assuming they are the same size.
