Measuring 300g of all-purpose flour without a scale

No scale? 300 g of all-purpose flour is about 2½ cups (2.5 cups), or roughly 2 cups + 8 tablespoons using standard US measuring cups and spoons. Spoon it in and level off the top instead of scooping, which packs in extra.

300 g of all-purpose flour comes to about 2.50 US cups, an exact two and a half cups. This is the typical flour for a standard sandwich loaf, a large tray of brownies or bar cookies, or a double batch of cookies for a crowd. It is also a common single-pizza-dough weight in many home recipes. The clean half-cup ending makes 300 g one of the easiest amounts to measure by volume if a scale is genuinely unavailable.
