Enter your pie pan diameter, crust type (single or double), and dough style (flaky, tender, or shortcrust) to get precise ingredient amounts. The Pie Crust Calculator outputs the exact weights of flour, fat, and liquid needed — scaled to your pan size so you never end up with too much or too little dough.

The calculator uses the area of your pie pan (based on diameter) plus the side depth and an overhang allowance to estimate the total surface area to be covered. It then uses the rolled thickness you select to compute the dough volume, which is converted to a weight. For a double crust, that weight is doubled.
Flaky crust uses a 3:2:1 ratio of flour to fat to liquid, producing distinct buttery layers. Tender crust uses slightly less fat and more liquid (3:1.8:1.2), yielding a softer bite. Shortcrust (3:2:0.9) uses less liquid, making a firmer, more crumbly crust often used for tarts and quiches.
A deeper pan has taller sides, which means more dough is needed to line the interior. Deep-dish pans (around 2 inches) require noticeably more dough than standard pans (around 1.25 inches) even if the top diameter is the same.
Butter is most common and adds flavor as well as flakiness. All-butter crusts are rich but can be slightly harder to work with. Shortening or lard produces a very tender, easy-to-roll crust. Many bakers use a 50/50 blend of butter and shortening for the best of both worlds.
Standard pie crust is rolled to about 3 mm (roughly 1/8 inch). Rolling it thinner (2.5 mm) gives a more delicate crust that browns faster, while a thicker roll (4 mm) is sturdier and holds up better to heavy fillings. The calculator adjusts ingredient amounts based on your chosen thickness.
Yes — simply keep in mind that the calculator outputs the exact amount for one pie. To scale up, multiply each ingredient weight by the number of pies you're making. Because pie dough freezes well, making a large batch and freezing individual portions is a great time-saver.
Salt (~1.5% of flour weight) is essential for flavor and is included in every style. Sugar (~2% of flour weight) is optional — it adds a subtle sweetness and promotes browning, and is more common in sweet fruit pies. You can omit sugar entirely for savory pies and quiches.
Because area scales with the square of the radius, a 9-inch pan has about 26% more area than an 8-inch pan. That means a recipe written for an 8-inch pan will leave you noticeably short if you try to use it in a 9-inch pan — which is exactly the problem this calculator solves.
