The Average Weight Range
For most commercially produced loaves, one slice of seeded bread weighs between 30 and 50 grams. This broad range exists because bread is not a one-size-fits-all product. Brands like Warburtons provide specific figures on their nutritional information, showing an average slice from their 800g seeded batch weighs 45.8g, while a slice from their smaller 400g loaf weighs 29.9g. Similarly, Hero Seeded Bread reports its slices weigh 37g, a testament to the fact that manufacturers define their own serving sizes and portion weights. For a simple point of comparison, the Federation of Bakers in the UK states that a typical slice of bread weighs around 38 grams.
What Determines the Weight of a Slice?
Multiple elements contribute to the final weight of a slice of seeded bread, making it crucial to look beyond a single, generic number.
- Loaf size: The total weight of the loaf is a primary indicator. A larger 800g loaf will be sliced more thickly to achieve a reasonable number of portions, resulting in a heavier individual slice compared to a smaller 400g loaf.
- Slice thickness: How the loaf is cut—whether medium-sliced, thick-cut, or thin-sliced—will directly impact the weight of each slice. A thicker slice contains more flour, water, and seeds, adding to its total mass.
- Seed concentration: The number, size, and type of seeds incorporated into the dough are major weight factors. Seeds like flax, sunflower, and pumpkin seeds are dense and add significant weight compared to an unseeded loaf of the same size.
- Moisture content: Water is a key ingredient in bread dough and contributes to the final weight. Bread that is baked and stored can lose moisture over time, causing a slight decrease in weight as it becomes stale.
- Flour type and density: The type of flour used, such as whole wheat versus white, can alter the density and structure of the loaf, which in turn affects the weight per slice.
Comparison of Seeded Bread Slice Weights
To illustrate the variability, here is a comparison of different seeded bread products based on available nutritional information. Weights are for a single slice.
| Brand | Loaf Size | Slice Weight | Citing Source |
|---|---|---|---|
| Warburtons Thick Seeded Batch | 800g | 45.8g | |
| Warburtons Seeded Batch | 400g | 29.9g | |
| Hero Seeded Bread | ~19.5 oz / 553g | 37g | |
| Tesco Finest Super Seeded Farmhouse | 800g | 44g | |
| Tesco Multiseed Batch | 800g | 50g | |
| Dave's Killer Bread | ~27 oz / 765g | 45g |
Why Does Seeded Bread Weigh More?
The inclusion of seeds, particularly those rich in protein, fat, and fibre, is the primary reason seeded bread tends to be heavier than a standard white slice. The added seeds not only provide a nutritional boost but also increase the overall density of the bread. For example, Hero Bread promotes its 37g slice as being heartier than a 30g slice of white bread. The concentration of these dense, nutrient-packed ingredients naturally increases the mass of each portion, justifying the higher weight found in many seeded options.
How to Accurately Weigh Your Bread Slice
For precise calorie counting or nutritional tracking, relying on an average weight is often insufficient. To get the most accurate information, consider these steps:
- Check the packaging: The nutritional information panel on the packaging is your best source for a declared average slice weight. This figure is based on a standard slicing of that particular loaf.
- Use a digital kitchen scale: For maximum accuracy, weigh your slice of bread on a digital scale. This is especially important for homemade bread, as slice thickness will vary.
- Note the brand and loaf size: Remember that the same brand can have different slice weights depending on the loaf size, so always double-check the product details.
Conclusion
The weight of one slice of seeded bread is not fixed but is a dynamic value influenced by manufacturing choices like loaf size and slice thickness, as well as the inherent density provided by seeds. While you can expect a slice to weigh between 30 and 50 grams, checking the packaging or using a kitchen scale provides the most accurate information for your specific loaf. This attention to detail is particularly valuable for those who monitor their dietary intake closely. The added seed content offers more nutritional benefit, which is reflected in its denser, and often heavier, nature.

Understanding the Factors at a Glance
- Typical Weight: The average slice of seeded bread weighs between 30g and 50g, though some products may fall outside this range.
- Seed Contribution: The density and type of seeds, such as sunflower and flax, increase the overall weight per slice.
- Slicing Variations: The thickness of the slice directly impacts its weight, with thicker cuts weighing more than thin-cut versions.
- Manufacturer Consistency: Different brands and loaf sizes produce varied slice weights, so consistency is not guaranteed across products.
- Nutritional Density: Seeded bread is often heavier due to added protein and fats from the seeds, making each slice more nutritionally dense.
- Moisture Loss: The water content in bread can decrease over time as it dries out, which affects its weight.
How Much Does a Slice of Seeded Bread Weigh? FAQs
Q: Is there a standard weight for a slice of seeded bread? A: No, there is no single standard weight. The weight varies significantly by brand, loaf size, and slice thickness, though many fall within a 30g to 50g range.
Q: Why does my slice of bread weigh differently than what's on the package? A: Bread is often sliced mechanically, and the end slices, or minor variations in the loaf, can lead to slight weight differences. For exact figures, a kitchen scale is the most accurate tool.
Q: Does seeded bread weigh more than white bread? A: Generally, yes. The added weight from dense, nutrient-rich seeds, such as flax, pumpkin, and sunflower seeds, makes a slice of seeded bread heavier than an equally sized slice of plain white bread.
Q: How does the weight of a seeded bread slice affect its nutritional value? A: A heavier slice of seeded bread will typically contain more calories, protein, and fat due to the added seeds. This is important to consider for those monitoring their intake.
Q: What is a common weight for a smaller loaf of seeded bread? A: For a smaller loaf, such as a 400g size, the average slice weight can be significantly lower, for example, around 29.9g.
Q: How can I find the precise weight of my seeded bread slice? A: The most reliable method is to use a digital kitchen scale to weigh an individual slice. This is particularly useful for homemade bread or for confirming package information.
Q: Does moisture loss impact the weight of seeded bread? A: Yes, as bread ages, it loses moisture, which causes its weight to decrease slightly over time. Fresher bread will be slightly heavier than older, drier bread.
Q: Are all brands' slice weights consistent across their products? A: No. As shown with brands like Warburtons, the same company may produce different loaf sizes with varying slice weights, even for the same type of bread.
Q: Does the type of seed impact the weight? A: Yes, different types of seeds have varying densities. While seeds generally increase weight, the specific mix of flax, sesame, sunflower, or pumpkin seeds will contribute to the final slice's weight.
