Garden Arch Calculator

Planning to build a beautiful archway for your garden but unsure how to calculate its dimensions? Whether you're using wood, metal, or bricks, knowing the correct measurements is crucial. That's why we created the Garden Arch Calculator – a simple, fast, and accurate tool to help you design your perfect archway with confidence.

Our calculator is ideal for homeowners, gardeners, and landscapers who want to find the exact area, height, and curve of an arch without needing to do complex math. This tool supports various arch types, including elliptical and semi-circular shapes.

What Is a Garden Arch Calculator?

The Garden Arch Calculator is an online tool that helps you calculate the dimensions of an arch based on input values like width, height, and thickness. It automatically calculates the arch rise, arch area in square meters, and other key data you’ll need to construct or order your garden arch.

Whether you're working with a metal garden arch, wooden arch, or even a brick garden arch, this calculator simplifies the process of planning and measuring.

How to Measure for a Garden Arch?

To use the calculator correctly, you first need to take some measurements:

• Span (Width): Measure the total horizontal distance between the base of the arch.
• Height (Rise): Measure the vertical height from the base to the top of the arch.
• Thickness (Optional): If your arch has a thick curve, include this measurement.

Once you have these values, input them into the Garden Arch Calculator to get your results instantly.

How to Calculate Arch Size?

Calculating the arch size manually can be difficult without the correct formula. The calculator uses standard formulas based on geometry. Here's a simplified version:

Formula for Semi-Circular Arch Area:

Area = (π × r²) / 2

Where r is the radius (half the span)

Formula for Elliptical Arch Area:

Area = π × a × b / 2

Where a = half of the width (semi-major axis)

And b = height (semi-minor axis)

Formula to Calculate the Rise of an Arch:

Rise = Height from the base to the top center of the arch

(For semicircular arches, Rise = Radius)

The calculator uses these formulas to give accurate and instant results. You don’t need to know advanced math just enter your dimensions, and you're done.

How to Use the Garden Arch Calculator?

1. Enter the width (span) of the arch in meters or feet.
2. Enter the height (rise) of the arch.
3. (Optional) Enter the thickness of the arch if applicable.
4. Click on the “Calculate” button.
5. Instantly get the arch area, rise, and required material estimates.

It’s that easy! The calculator works for elliptical, semicircular, and custom arches alike.
