Peanut butter: cup, tablespoon and jar sizes
Peanut butter is thick and traps air, so press it firmly into the cup and level the top — a properly packed cup is about 258g (9 oz). A tablespoon is roughly 16g, and the familiar 2-tablespoon serving on the label is about 32g.
Working from a jar instead of a recipe? A 16 oz (454g) jar holds about 1¾ cups, a 12 oz jar about 1⅓ cups, and a big 28 oz jar about 3 cups. Natural and no-stir styles weigh about the same once stirred smooth.

Is peanut butter heavy or light for its category?
A cup of peanut butter weighs 258 g, which puts it 3rd by weight among the 10 syrups & spreads on this site. Its nearest neighbours are almond butter at 256 g and hazelnut spread at 296 g per cup.
Swapping these by the cupful is not like-for-like. A cup of hazelnut spread in place of peanut butter puts roughly 38 g more in the bowl, so match the grams rather than the cups.
