An 8x3 inch round pan holds about 9 cups (2¼ quarts, 2.1 L) filled to the brim — about 6 cups of batter at the usual two-thirds fill.

2¼ quarts · ≈ 2129 ml / 2.1 L · batter at ⅔ fill ≈ 6 cups
Data & method: Estimate: Joy of Baking doesn't list an 8×3″ round, so this is its 8×2″ round (6 cups) scaled to 1½× the depth.
Batter fill is the standard two-thirds convention; quarts and metric are exact US-cup
conversions (4 cups = 1 quart). The calculations are covered by automated tests. How we calculate →

Fill level
The calculator reports pure geometric volume — straight sides filled to the very
top — so for this pan it shows about 10.4 cups against the estimated 9. Charted capacities run lower because real pans have sloped sides and rolled rims.
Both are correct; they answer slightly different questions.
Nothing in the standard chart lands within 10% of the 3"-deep 8" round's 9-cup capacity, so there's no clean straight swap — rescale
the recipe to the pan you have instead. The cake pan converter
gives the exact multiplier and the bake-time shift for any pair.
Filling guidance: two-thirds is the working rule for butter and oil cakes. Batters with big
oven spring — angel food, chiffon, some sponges — want more headroom, and dense batters
(brownies, blondies) tolerate fuller pans because they barely rise.
About 9 cups filled to the brim (about 2129 ml / 2.1 liters). Estimate: Joy of Baking doesn't list an 8×3″ round, so this is its 8×2″ round (6 cups) scaled to 1½× the depth. For batter, fill to about two-thirds: roughly 6 cups, leaving room to rise.
How many quarts does an 8x3 inch round pan hold?
About 2¼ quarts — 9 cups filled to the brim, since a US quart is exactly 4 cups. That's about 2.1 liters.
How many cups of batter go in an 8x3 inch round pan?
About 6 cups — the standard two-thirds fill. Fuller than that and rising batter can overflow; much less and the bake comes out thin and dries. Cakes with big oven spring (angel food, some sponges) want even more headroom.
What can I substitute for an 8x3 inch round pan?
Nothing in the standard chart lands within 10% of its 9-cup capacity, so a straight swap isn't clean — scale the recipe to the pan you have instead. The cake pan converter gives the exact multiplier for any pair.
Is the pan's stamped size the inside measurement?
It should be — pan sizes refer to interior top dimensions. Measure inside edge to inside edge, and depth from the interior base to the rim. Outside measurements add the metal's thickness and rolled rims, which overstate the pan.
