How I Figure Out the Right Dough Amount for Any Loaf Pan

For fresh milled whole grain bread, the easiest way to size dough is to use about 60% of your loaf pan’s water capacity.

How Much Dough Should Go in a Loaf Pan?

One of the most common questions I get is:

“How much dough should I put in this pan?”

If you’re baking with 100% fresh-milled whole grain flour, most of the answers out there just don’t work very well. So I want to walk you through exactly how I do it, step by step, using a method that works with any loaf pan, shape, or dough hydration — even if your pan isn’t a “standard” size.

I want to keep this simple.
No complicated math. I promise.


The Big Idea (Before We Start)

Instead of guessing how much flour to use, I let the pan tell me how much dough it wants.

The simplest way to do that is with water.

Water is easy to measure, and it gives us a number we can work from every single time.

Recommended equipment:
Waterproof rechargeable digital scale

My favorite bread pans:
Lodge cast iron loaf pans


Step-by-Step: Let the Pan Decide

  1. Put your pan on a gram scale and press the tare / zero button.
    The scale is ready when it shows 0 grams.

  2. Fill the pan all the way to the top with water — right up to the rim.
    When the water settles, write down the number in grams.
    That number is your pan’s total water capacity.

  3. Calculate the ideal dough weight

    For 100% fresh-milled whole grain bread, I use 55–65% of the pan’s water capacity as my final dough weight.

    To keep things simple for beginners, I start right in the middle:
    60% of the pan’s water capacity

    Multiply your number from Step 2 by 0.60 and that’s your ideal dough weight.


A Real Example

Let’s say your pan holds 1,420 grams of water.

1,420 × 0.60 = 852 grams of dough

That amount of dough will fill the pan nicely for most whole-grain loaves.

If numbers make you nervous, just remember this:

Fill the pan with water.
Multiply that number by 0.60.
Make that much dough.

That alone will get you baking confidently.


Want to Fine-Tune Later? Hydration Matters

Once you’re comfortable, you can adjust where you land in the 55–65% range based on how wet your dough is.

Here’s a general guideline:

Dough hydration

Use about

80–85% (firmer, beginner-friendly)

55–58%

90–100% (soft sandwich bread)

58–62%

105–120% (very soft, extra moist)

62–65%

Notice that the amount of dough to fill the pan increases as the water increases.
