Which Gravel Is Best For You?


With so many different options out there, it can be hard to decide which gravel is best for you. Not only are there numerous colours and types, there are also different sizes, which are important to get right for your project. Online Gravel have compiled a guide to help you decide which gravel is for you.

GRAVELS From shingle to pebbles, gravel is screened and categorised into many different sizes and each one is recommended for different purposes, some of which can be found below - from the smallest to the largest.

10mm Gravel is perfect for:

Pathways - The smaller shingles compact down better than the larger pebbles, making them much easier to walk on. Although, be aware that if your garden path leads straight to the backdoor, you may find the smaller stones get walked into the house.

Flower Beds and Pots - Gravel makes very attractive flower beds and can add interest to your plant pots. This smaller gravel also has the added benefit of working as a mulch, meaning it insulates your plants in the winter and helps to stop evaporation.

General Decoration - If you are looking to add a splash of colour to any area, 10mm gravel is considered by many to be more decorative than the larger sizes.

We do not really recommend using 10mm gravel on driveways. Its smaller size means that it will get stuck in car tyres and driven away, leaving you with less and less gravel on your drive. However it is all down to personal preference.

20mm gravel is great for:

Driveways - This is the most popular sized gravel for driveways. It’s larger size means that it is unlikely to get stuck in car tyres and will stay where you need it to.

Rockeries - If you’re considering a rockery, larger gravels are best used as they won’t move as much.

Water Features - Larger gravels look more effective under water, although if they’re being used in ponds, make sure the gravel you choose is fish friendly.

For pathways, although the 20mm gravel is less likely to be kicked onto lawns and flower beds, it is harder to walk on than the smaller gravels.


14mm granite is ideal for:

Pathways - The inherent hardness of granite means it is great for paths that are going to see quite a lot of foot traffic. As it is slightly larger than the 10mm gravel you may find that it stays were it is meant to a bit better.

Driveways - As the granite falls between the small and large sized gravels, it works equally well on driveways as well.

General Decoration - Granite tends to have fewer colour varieties in each batch than gravels, therefore if you are looking for garden decoration, it can create quite a striking effect.


40mm Slate is perfect for:

Pathways - As slate is a naturally flat stone, it is ideal for walking on. It can also be used on a driveways, but ideally these pieces need to be a big as possible to stop them from being crushed.

Water Features - Slate looks even better when it is wet and as it is fish friendly it is perfect for all water features.

Flower Beds and Borders - Slates are quite good at suppressing weeds in flower beds, and also insulates your plants in the winter, making it effective in your borders.


20-40mm Scottish Pebbles are great for:

Flower Beds & Borders - Lots of people like to use these larger stones in their flower beds as they can be more interesting that your traditional gravels.

Water Features - As Scottish Pebbles have been gradually rounded by the sea over thousands of years, they make perfect decoration for water features, particularly as they are also fish friendly.

General Decoration - Their unique appearance ensures Scottish Pebbles look great wherever they are placed

As they are much larger than traditional gravels, but still retain the rounded nature unlike the slate, it is not recommend to use Scottish Pebbles on pathwa
