Understanding your recommendation

Standard Configuration

Your selected dimensions match one of our official standard raised bed configurations.

For a single bed, the calculator recommends the matching kit directly.

Custom Modular Combination

For custom sizes, multiple beds, or optimized quantities, the calculator may combine Large and Jumbo kits. Medium kits remain available only for official standard configurations.

This recommendation is designed to cover the requested layout while reducing leftover panels and corners where possible.

Custom size recommendations

How the calculator works

Our Custom Raised Garden Bed Calculator helps you find the best modular kit combination for your desired garden bed layout.

Select your preferred bed height, then enter the length, width, and number of beds you would like to build. You can also add multiple bed sizes if your project includes more than one layout.

If your selected size matches one of our official standard configurations, the calculator may recommend the matching kit directly. For multiple beds or custom layouts, it will look for the most efficient combination of Medium, Large, and Jumbo kits based on the available straight panels and curved corners.

Important Notes & Limitations

  • The calculator is designed for standard rectangular raised bed layouts only.
  • Supported custom sizes range from 2ft–24ft in length and 2ft–4ft in width.
  • Each final bed uses curved corners, which are included in the final dimensions and tracked separately from straight panels.
  • Custom recommendations may combine Medium, Large, and Jumbo kits to reduce leftover panels and corners.
  • Some recommendations may still include leftover parts, especially when extra corners are needed to build multiple beds.
  • Recommendations are estimates based on available kit contents and modular compatibility.
  • Certain custom layouts may require manual adjustment during assembly.
  • For larger, complex, or highly customized projects, please contact our team and we’ll help determine the best configuration for your setup.
