Whether you’re ordering a resin bound kit, decorative aggregates or planning a new installation, knowing the correct area is essential. Ordering too little material can delay your project, while ordering too much increases costs and creates unnecessary waste.

The good news is that calculating the area of most driveways and patios is straightforward. In this guide, we’ll explain how to measure different shapes, calculate square metres (m²), and introduce a few useful apps that can make measuring even easier.

Why Accurate Measurements Matter

Resin bound materials are supplied based on square metres (m²) at a specific installation thickness.

Accurate measurements help you:

• Order the correct quantity of materials
• Reduce waste
• Calculate project costs accurately
• Plan deliveries
• Estimate installation time

Even a small measuring error can make a significant difference on larger projects.

Step 1 – Measure the Length and Width

The easiest areas to measure are rectangles and squares.

Simply measure:

• Length (m)
• Width (m)

Formula

Area = Length × Width

Example

Driveway Length: 10 metres

Driveway Width: 5 metres

10 × 5 = 50m²

Your driveway area is 50 square metres.

Step 2 – Divide Irregular Shapes into Smaller Areas

Many driveways aren’t perfect rectangles.

L-shaped driveways, curved paths and wider parking bays can easily be measured by dividing the area into simple shapes.

For example:

• Rectangle
• Square
• Triangle
• Circle (or part circle)

Calculate each section separately before adding them together.

This method usually provides excellent accuracy without complicated calculations.

Calculating Triangles

Many driveways have triangular sections.

Use the formula:

Area = Base × Height ÷ 2

Example:

Base = 4m

Height = 3m

4 × 3 ÷ 2 = 6m²

Calculating Circular Areas

For circular seating areas or turning circles use:

Area = π × Radius²

Example:

Diameter = 6m

Radius = 3m

3 × 3 × 3.142

= 28.3m²

Measuring Curved Driveways

Curved driveways can often be divided into several rectangles and triangles.

For complex curves:

• Take several measurements.
• Split into smaller sections.
• Round up slightly when ordering materials.

Professional installers often add a small allowance to ensure sufficient material is available.

Don’t Forget Borders

If your project includes contrasting borders, measure these separately.

For example:

Main area:

45m²

Border:

8m²

Order each colour independently.

This produces far more accurate quantities.

Allow for Waste?

One advantage of resin bound surfacing is that waste is usually minimal when measurements are accurate.

However, depending on the complexity of the design, it is sensible to allow a small contingency.

For professional installations, an additional 3–5% is often sufficient for intricate shapes or unexpected site conditions.

Useful Apps for Measuring Areas

Technology has made measuring much easier.

Several apps allow you to measure directly from satellite imagery or using your smartphone.

Google Maps

Ideal for measuring driveways and larger areas.

You can use the built-in measuring tool to calculate distances and estimate areas.

Best for:

• Existing properties
• Large driveways
• Commercial projects

Google Earth Pro

One of the most accurate free tools available.

Allows polygon measurements directly from aerial photography.

Excellent for:

• Large commercial sites
• Housing developments
• Landscape projects

Measure (iPhone)

Many newer iPhones include Apple’s built-in Measure app.

Using augmented reality, it allows you to measure lengths directly from your phone.

Ideal for:

• Patios
• Paths
• Small driveways

MagicPlan

A professional app that creates plans while measuring.

Ideal for contractors who regularly produce quotations.

Features include:

• Floor plans
• Area calculations
• PDF reports
• Project storage

Measure Map

A popular app for measuring land directly from aerial photographs.

Particularly useful for:

• Large gardens
• Commercial sites
• Landscaping projects

Bosch MeasureOn

Designed for use with Bosch laser measuring equipment.

Ideal for professional installers requiring highly accurate measurements.

Laser Distance Measurers

For the highest accuracy, many professional contractors use laser distance measurers.

They offer:

• Fast measurements
• High accuracy
• Easy one-person operation
• Digital recording

They’re particularly useful for larger driveways and commercial projects.
