Cornmeal:
grams to cups.
Cornmeal weighs 138 g per cup — denser than most flours because coarse corn particles pack more tightly than fine-milled wheat. The grind size of your cornmeal makes a noticeable difference in both cup weight and final texture.

Fine vs coarse grind and how it shifts the cup weight
Cornmeal sold in stores ranges from fine-ground (nearly flour-like) to coarse stone-ground. Fine cornmeal packs more densely in a measuring cup, potentially reaching 145–150 g per cup. Coarse cornmeal, with larger grit particles, leaves more air gaps and may weigh closer to 130 g per cup. The 138 g/cup figure applies to medium-grind commercial cornmeal — the most widely available type. Stone-ground whole-grain cornmeal sits at the coarser end. If your recipe was developed with a different grind, a cup-for-cup substitution may over or under-deliver cornmeal, changing the texture of your cornbread from tender and moist to crumbly and dry.
Cornmeal in cornbread: where density errors show up
Cornbread recipes are particularly sensitive to cornmeal quantity because cornmeal both provides structure and absorbs liquid. Too much cornmeal — from over-packing the cup — produces dry, crumbly cornbread that falls apart when sliced. Too little produces a wet, gummy center. Southern cornbread recipes, which often use a higher ratio of cornmeal to flour than Northern recipes, amplify this sensitivity. When a cornbread recipe specifies the grind type, match it exactly; if it doesn't, assume medium-grind and weigh 138 g per cup called for.
Frequently asked questions
- How many grams is 1 cup of cornmeal?
- 1 cup of medium-grind cornmeal weighs 138 g. Fine cornmeal may weigh up to 150 g per cup; coarse stone-ground may weigh around 130 g.
- Is cornmeal heavier or lighter than all-purpose flour per cup?
- Heavier — cornmeal weighs 138 g per cup versus 120 g for all-purpose flour. The coarser corn particles pack more densely than finely milled wheat.
- How many cups is 200 g of cornmeal?
- 200 g ÷ 138 g/cup ≈ 1.45 cups — about 1.5 cups minus 1 tablespoon.
