Salt Dough Calculator — Recipe Scaler
Scale the classic salt dough recipe to any size in seconds. The traditional ratio is 2 parts flour to 1 part salt to 1 part water by volume. Enter the number of batches and choose cups or grams — the calculator gives you exact amounts for each ingredient.
Measurement unit
Approximate total weight in grams (flour + salt + water)
- 1
Flour weight
1 × 2 cups × 125 g/cup = 250 - 2
Salt weight
1 × 1 cup × 292 g/cup = 292 - 3
Water weight
1 × 1 cup × 237 g/cup = 237 - 4
Total dough weight
250 + 292 + 237 = 779
How does this calculator work?
Mix 2 parts flour, 1 part salt and 1 part water by volume (2:1:1 ratio). One batch = 2 cups flour, 1 cup salt, 1 cup water. Scale by the number of batches. Knead until smooth, shape and bake at 100–120 °C until hard, or air-dry for 1–3 days.
Formula
How this is calculated
Salt dough is made from just three pantry ingredients in a fixed 2:1:1 ratio by volume — two parts all-purpose flour, one part table salt and one part water. The salt preserves the dough and slows mould growth; the flour provides structure; and the water binds everything into a workable clay. The ratio is the same whether you are making a handful of Christmas ornaments or a large school project — you simply scale all three ingredients by the same factor.
The calculator uses the standard one-batch baseline of 2 cups flour, 1 cup salt and 1 cup water. Select cups for a straightforward kitchen measurement, or grams if you prefer to weigh ingredients on a scale (gram weights are approximate averages — flour weight varies with how it is scooped and sifted; the values shown here use 125 g per cup for flour, 292 g per cup for table salt and 237 g per cup for water).
To make the dough: combine dry ingredients (flour and salt) first, then gradually add water and knead for a few minutes until smooth and pliable. The dough can be air-dried (1–3 days), oven-baked at 100–120 °C (210–250 °F) for 1–3 hours depending on thickness, or microwave-dried in short bursts. Seal finished pieces with clear varnish or acrylic to prevent moisture absorption.
Frequently asked questions
One standard batch (2 cups flour, 1 cup salt, 1 cup water) yields roughly enough dough for 10–15 small ornaments rolled to about 5 mm (¼ inch) thick. For a class of 30 children each making one ornament, start with two or three batches.
Fine table salt works best and gives the smoothest texture. Coarse sea salt or kosher salt can be used but may not dissolve fully, leaving a rougher surface. If substituting, use the same cup volume but expect slight texture differences.
Oven-baking at a low temperature (100–120 °C / 210–250 °F) for 1–3 hours is the most reliable method. Air drying takes 1–3 days and may cause cracking in thicker pieces. Microwave drying works for thin pieces in short bursts. Flip pieces halfway through baking to dry evenly.
