Best Kitchen Scales for Meal Prep UK

A cheap digital kitchen scale is one of the lowest-cost, highest-impact purchases for anyone serious about meal prep. This guide covers what to look for and the most common mistake people make once they own one.

Most people underestimate portions of calorie-dense foods like oils, cheese, nuts and pasta, and overestimate portions of lower-calorie foods like vegetables. Weighing removes this bias entirely and is the single most reliable way to hit a specific calorie or protein target consistently.
It also matters for consistency between meals. Two "handfuls" of rice can vary by 50g or more depending on the day, which adds up to a meaningfully different weekly intake even if every other choice stays the same.
What To Look For In A Meal Prep Kitchen Scale
A tare (zero) function is essential, letting you weigh multiple ingredients into the same bowl by resetting to zero between each one. A capacity of at least 3kg covers most meal prep needs, and a flat, wipeable platform is easier to keep clean than a bowl-style scale.
Cooked Vs Raw Weight: A Common Confusion
This is the single most common mistake once people start weighing food. Rice roughly doubles in weight when cooked, pasta increases by around 2-2.5 times, and meat typically loses 20-25% of its weight during cooking as moisture evaporates.
| Food | Typical raw-to-cooked change | Practical note |
|---|---|---|
| White rice | Roughly doubles (x2) | 75g raw becomes about 150g cooked |
| Pasta | Increases roughly x2.2-2.5 | 75g raw becomes about 170-190g cooked |
| Chicken breast | Loses roughly 20-25% | 150g raw becomes about 115-120g cooked |
| Minced beef | Loses roughly 25-30% (fat and water) | Varies more depending on fat content |
How To Use A Scale To Hit A Calorie Or Protein Target
Weigh the raw ingredient, note the weight, and use nutrition figures for that raw weight rather than guessing after cooking. If a recipe or meal plan states a cooked weight, weigh the finished dish instead and be consistent about which method you use so figures stay comparable week to week.
Frequently Asked Questions
Should I weigh food raw or cooked?
Raw, unless a specific recipe or meal plan states a cooked weight. Most standard nutrition figures are based on raw weight for foods like rice, pasta and meat.
Do I really need a kitchen scale for meal prep?
Not strictly, but it is one of the most reliable ways to hit a consistent calorie or protein target, since portion sizes by eye vary more than most people expect.
What capacity kitchen scale do I need?
A 3-5kg capacity covers almost all home meal prep needs, including weighing a full batch of rice or pasta in one go.
