At 2 inches deep, the round pan holds about 127 in\u00b3 and the rectangle holds 234 in\u00b3. Divide the second by the first and you get <strong>\u00d7 1.84<\/strong>.<\/p>\n        <p>So a recipe with 2 cups of flour needs about 3\u2154 cups, and 1\u00bd cups of sugar becomes about 2\u00be cups. Every ingredient gets the same multiplier. Use the recipe scaler to do the whole list in one go.<\/p>\n      <\/div>\n\n      <div class=\"mmc-dp-ex\">\n        <span class=\"mmc-dp-tag\">2 \u00b7 Going smaller: a 9 \u00d7 13 to an 8 \u00d7 8<\/span>\n        <p>An 8 \u00d7 8 pan at 2 inches deep holds 128 in\u00b3, which is 0.55 of the 9 \u00d7 13. So you need a bit more than half the recipe. A straight half would leave your pan a little under-filled, and the cake would come out shallower than the recipe intends, so check it early.<\/p>\n      <\/div>\n\n      <div class=\"mmc-dp-ex\">\n        <span class=\"mmc-dp-tag\">3 \u00b7 Same, different shape<\/span>\n        <p>A 9-inch round and an 8-inch square hold almost exactly the same amount (127 against 128 in\u00b3).

That depends on how deep the batter ends up in the pan.<\/p>\n      <ul>\n        <li><strong>Fill the pan about half to two-thirds full.<\/strong> Cakes rise, and a full pan overflows or sinks in the middle.<\/li>\n        <li><strong>Shallower batter bakes faster.<\/strong> Check about a quarter of the time early.<\/li>\n        <li><strong>Deeper batter bakes slower.<\/strong> Bake longer and drop the oven by 10\u201315 \u00b0C (about 25 \u00b0F), so the outside doesn't brown before the middle sets.<\/li>\n        <li><strong>Same depth?<\/strong> Keep the temperature and the time, and start checking at the early end of the range.<\/li>\n      <\/ul>\n\n      <h2>Pans that don't follow the maths<\/h2>\n      <ul>\n        <li><strong>Bundt and tube pans.<\/strong> The tube in the middle takes up space, so the pan's shape doesn't follow a simple formula. Use the capacity marked on the pan, usually in cups.<\/li>\n        <li><strong>Springform pans.<\/strong> They hold what a round pan of that size holds, but they can leak thin batter. Put a tray under them.<\/li>\n        <li><strong>Loaf pans.<\/strong> They're tall and narrow, so the middle cooks slower than the edges. Expect a longer bake than a flat pan of the same volume.<\/li>\n        <li><strong>Muffin tins.<\/strong> Each cup is filled about two-thirds, which is roughly \u2153 cup of batter. As a rough guide, a recipe for two 9-inch layers usually makes around 24 cupcakes.<\/li>\n        <li><strong>Dark metal, glass and silicone.<\/strong> Dark metal pans brown faster and glass dishes hold heat. For both, many bakers lower the oven by about 15 \u00b0C (25 \u00b0F). Silicone doesn't brown much at all.<\/li>\n      <\/ul>\n\n      <h2>How to measure a pan properly<\/h2>\n      <p>Measure across the <strong>inside<\/strong> of the pan, from one inner edge to the opposite one, at the top. Don't include the rim. Measure the depth from the inside base to the rim. A pan sold as \"9-inch\" can measure a little over or under, and older pans are often a different size from today's, so a quick measure beats trusting the label.<\/p>\n\n      <div class=\"mmc-dp-why\">\n        <span class=\"mmc-dp-tag\">Why this matters<\/span>\n        <p>Most baking disasters with the wrong pan come from two things: too much batter for the pan, and a bake time that was written for a different depth.

If it is deeper, bake longer and lower the oven by 10 to 15 \u00b0C (about 25 \u00b0F) so the outside does not burn before the middle is set. If the depth stays about the same, keep the same temperature and time, and start checking at the earlier end of the range.<\/p>\n        <\/details>\n              <details>\n          <summary>How full should I fill a cake pan?<\/summary>\n          <p>Fill the pan about half to two-thirds full.
