Simplest Gravel Calculator In The UK

For example, if you want to cover 1m2 (1 meter x 1 meter) of your area of depth 50mm, you will need approximately 100kg of pebbles or gravel. On the other side, the depth of 30mm will need 60 kilograms. However, we do recommend a depth of at least 50mm for better results.
Fraction 10/30mm 30/60mm 60/100mm
1m2 3 Bags (50-60kg) 4 Bags (60-80kg) 5 Bags (80-100kg)

How much does a 20kg bag of gravel cover?

As heavy as it may sound, 20 kilograms or 50 pounds is not a lot when we look at the area we want to decorate in meters squared. Therefore, it is essential to understand the weight factor. For example, 20 kilograms of pebbles may cover only 0.5m2, and please do remember it does vary on the depth of the gravel or aggregate used. Do not feel discouraged. The final results are excellent!
