River Gravel (5mm)

5mm river gravel is a small, smooth stone that creates a neat, natural finish while allowing excellent drainage. It is commonly used for:

• Decorative garden beds
• Pathways and walkways
• Pot and planter drainage
• Around stepping stones
• Water features and ponds
• General landscaping and ground cover

Yes. 5mm river gravel is a great choice for garden paths because it provides a natural appearance and a comfortable walking surface. Many people choose a smaller stone like this as an alternative to deco.

Just keep in mind that, due to its small, rounded shape, it can move underfoot more than crushed stone. We recommend installing suitable garden edging to help keep the gravel contained and maintain a neat finish.

To calculate how much 5mm river gravel you need for your project, measure the length and width of the area where the stones will be placed.

Next, determine the desired depth of the stones. The required depth will vary depending on your project and the area you need to cover.

Once you have your length, width, and depth measurements, you can use our cubic metre calculator above or calculate the volume manually using the following formula:
Volume = Length × Width × Depth

Recommended Depth: As a general guide, we recommend laying decorative stones at a depth of 40–50mm. However, the ideal depth will depend on your project and the size of the stones. Larger stones may require a deeper layer for even coverage, while smaller stones can often be laid slightly thinner.

Yes. 5mm river gravel is an excellent choice for pots and planter boxes. Its small, smooth stones create a subtle, natural look that complements pots of all shapes and sizes.

The pea gravel size makes it easy to create an even layer across the surface of the pot while also improving drainage. It provides a clean, consistent finish that blends beautifully with a wide range of landscaping styles.
