How thick to roll gingerbread dough for a house
The recipes I opened disagree: King Arthur rolls 1/8 in, Food Network 1/4 in, and the White House Historical Association writes that walls should be 3/8 to 1/2 in. I would start with 1/4 in for a house up to about 8 in wide. That cutoff is my own rule of thumb. This page lists what each source says about thickness and baking, then shows what the thickness does to the dough you mix and to the wall pieces you cut.
What four sources say
| Source | Rolled to | Oven | Bake time |
|---|---|---|---|
| King Arthur | 1/8 in (3 mm) | 350°F | 10–12 min |
| Ottolenghi | about 4 mm | 180°C fan | 12–15 min |
| Food Network Kitchen | 1/4 in (6 mm) | 350°F | 20–25 min small pieces, 25–28 min all |
| White House Historical Association | walls 3/8–1/2 in, roof 3/8 in | 350°F | about 25 min for a half sheet |
Thickness and bake time go together. The thin King Arthur and Ottolenghi doughs are done in 10 to 15 minutes, and the 1/4 in dough needs 20 to 28 minutes. Food Network drops the oven to 300°F for its extra-large mansion pieces and adds 15 to 20 minutes. Three of them judge by the dough itself: King Arthur says "set and very lightly browned at the edges", Ottolenghi says until the edges start to colour, and Food Network says the centers should be firm to the touch. The White House page gives only a time. Food Network also suggests baking a few minutes longer when unsure, because the pieces have to be strong.
Two practical tips from those pages: Food Network lays 1/4 in dowels on both sides of the dough so the rolling pin stays level, and the White House page suggests two wooden boards the thickness of the walls and roof. Both give an even sheet without measuring each time.
The recipes also differ in more than thickness. King Arthur calls its dough construction gingerbread, with extra flour to make it sturdier. My guess is that this is why it can be rolled as thin as 1/8 in. Use the thickness that goes with your own recipe.
What thickness does to a 6 in wide house
Dough thickness changes two things you can count. The dough weight is linear in thickness, so 1/2 in dough takes four times the dough of 1/8 in. And at each corner one wall overlaps the other by one thickness, so the cut sizes move. This table is the classic 6 × 8 × 4 in house with a 45° roof, side walls fitted between the front and back walls (the inside joint):
| Thickness | Side wall | Roof panel | Dough with extra | Food Network Kitchen batches | King Arthur batches | Template |
|---|---|---|---|---|---|---|
| 3.2 mm (0.125 in) | 7.75 × 4 in | 9 × 4.74 in | 656 g | 0.4 | 0.5 | Open |
| 4.8 mm (0.1875 in) | 7.63 × 4 in | 9 × 4.74 in | 979 g | 0.6 | 0.7 | Open |
| 6.4 mm (0.25 in) | 7.5 × 4 in | 9 × 4.74 in | 1,299 g | 0.8 | 1 | Open |
| 7.9 mm (0.3125 in) | 7.38 × 4 in | 9 × 4.74 in | 1,616 g | 1 | 1.2 | Open |
| 9.5 mm (0.375 in) | 7.25 × 4 in | 9 × 4.74 in | 1,930 g | 1.2 | 1.5 | Open |
| 12.7 mm (0.5 in) | 7 × 4 in | 9 × 4.74 in | 2,549 g | 1.5 | 1.9 | Open |
Dough is the area of all pieces times thickness, with 25% extra for trimmings. Batch weights are my estimates from the ingredient lists, explained in the dough guide. A thicker roll uses more batches than a recipe's stated yield.
The corner effect is small. The side wall for the 1/8 in dough is cut 7.75 in long, and for the 1/2 in dough 7 in, because each end gives up one thickness to the gable wall. If you cut by a template made for thin dough and then roll thick, the house comes out too long. The generator takes the thickness as an input, so the printed pieces fit the dough you roll.
Going from 1/4 in to 3/8 in takes the classic house from 1,299 g to 1,930 g of dough. The baking sheets stay the same, since the pieces keep their outline. By my reading, only the bake time grows: the White House page gives about 25 min for its 3/8 to 1/2 in dough.
Which thickness for which house
For a house up to about 8 in wide, 1/4 in is the one I would pick, and it matches the Food Network recipe. For a thin, light house such as one that sits on a mug, 1/8 in works, and the mug house guide uses it. For a centerpiece with long walls, the White House page gives 3/8 to 1/2 in for walls, and I would read the large house guide for pans and supports.
Whatever you pick, roll it evenly. I expect a wall that is 1/4 in at one end and 1/8 in at the other bakes unevenly, warps and leaves gaps at the joints. After baking, let the pieces cool flat and, for large houses, rest them overnight before assembly, as Food Network recommends. The assembly guide covers the icing and the order of the walls.
Print pieces for your thickness
Open the template generator with the classic house at 1/4 in, or type your own size and thickness. Common sizes are in the dimensions guide, and what a village of houses needs is in the dough guide.
