In this article, I’ve put together a complete guide on how many loaves of bread you can expect to get from a bag of flour, for various bag and loaf sizes.
As a quick example, a standard small loaf contains 300g/10.58oz of bread flour and a standard large loaf contains 500g/1.1lb of flour, so a 1kg/2.2lb bag of flour would produce three small loaves or two large loaves.
Bag sizes vary across different countries, especially between the USA where the imperial weight system is used, and other countries that use the metric system such as the UK and Australia.
Read on to see many more conversions for both metric and imperial flour bag weights with quick reference charts to help you find the information relevant to you.

How Many Loaves Of Bread Can You Make From Standard Bags Of Flour?
In this section, I’ll show you the standard sizes of bags of flour that you can expect to find in stores and supermarkets, along with how many small or large loaves you can get from each bag size.
This is split out into imperial (pounds and ounces) and metric weights (kilograms and grams), depending on the weight system used in your country.
Imperial Flour Pack Weights To Loaves
The chart below shows standard flour pack sizes for the USA where the imperial weight system is used, along with conversions into metric weights:
| Bag of flour weight (as sold) | Weight in ounces | Metric conversion |
| 2lb | 32oz | 907g / 0.9kg |
| 3lb | 48oz | 1361g / 1.36kg |
| 5lb | 80z | 2268g / 2.27kg |
| 10lb | 160oz | 4536g / 4.54kg |
Based on these standard imperial flour pack sizes, the chart below shows how many loaves you can expect to get from each pack size.
This chart is based on a standard small loaf recipe using 300g/2.5cups of flour and a large loaf using 500g/4.2cups of flour per loaf.
It’s important to note that some recipes may require more or less flour, these figures are based on standard amounts.
| Bag of flour weight (as sold) | Number of Small Loaves per bag | Number of large Loaves per bag |
| 2lb | 3 | 1.8 |
| 3lb | 4.5 | 2.7 |
| 5lb | 7.6 | 4.5 |
| 10lb | 15 | 9 |
Metric Flour Pack Weights To Loaves

Flour Pack Weights Converted To Cups
If you prefer to measure your bread ingredients using cups then here are the conversions for standard bags of flour to US cups.
This is based on an average cup of bread flour weighing 120g per cup, which means a standard small loaf contains 2.5 cups of flour per loaf and a standard large loaf contains 4.2 cups of flour per loaf.
You can then use the charts above to work out how many loaves you can expect for each bag weight.
