Calculate Bread Dough To Fit Your Pan

Math is definitely not my best subject. I have come to learn that it's always easier to do the math than just eyeball it.  I typically use grams per square inch. If you have a pan that you always bake in and like the results than use that as your base calculation. I calculate the area of the pan and divide the weight of the ball of dough by the number of square inches yielding grams per square inch (grams/sq. in.). This will give you a constant ratio that you can use for any pan so the dough will fill out the pan properly.

Then I take the area of the new pan and calculate the area in square inches then multiply by your grams/sq. inch ratio.

Example:
Original recipe pan size: 10x10 in. 10x10 = 100 square inches
Weight of the dough ball: 400 grams.
Grams/square inch = 400 grams divided by 100 square inches = 4 grams per square inch. This is your constant for all your pans.

So now I want to use this totally different pan for the  same bread ... here is how much dough I need.
New pan size: 12x12in. 12x12 = 144 square inches.
Dough for 12x12 pan = 144 square inches    
(144 x 4 your ratio) = 576 grams of dough.

Hope this helps.
