Record a rectangular raised-bed fill scenario from approved inside dimensions, an entered top-up allowance, and the exact current package volume.
Choose your path
Record one rectangular raised-bed fill and exact-package scenario from approved inside geometry, an entered top-up allowance and the current package volume without selecting depth, media, structure or drainage.
Translate the real inside fill space into a documented base and planned volume.
Measure inside length/width, copy the approved fill depth and enter only a supported top-up allowance.
Gets auditable cubic feet/yards without a universal depth, settlement percentage or media recipe.
Convert the planned volume into whole packages using the current label.
Copy the exact usable package volume and compare capacity above the plan.
Avoids an assumed bag size or automatic ten-percent purchase instruction.
Keep geometry separate from suitability and safe installation.
Review the result with actual layers, structure, drainage, media source, contamination, access, delivery and settlement evidence.
Does not treat package arithmetic as bed, crop, food-safety or procurement approval.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
This tool is part of these guided projects. Each project provides step-by-step instructions with checklists and all the tools you need in one place.

Multiply length, width, and depth in the same units. For feet and inches, convert depth to feet first.
volume (cu ft) = length (ft) × width (ft) × depth (ft)Bulk soil is often sold by the cubic yard. One cubic yard equals 27 cubic feet.
cubic yards = cubic feet / 27No universal settlement percentage or bag size is applied. Enter 0% unless the exact media, layering and settlement plan supports an allowance, then divide by the usable volume printed for the exact current package.

Enter a 3-inch refresh depth instead of full fill when renewing soil in existing frames.
Use deeper fill depth for carrots and potatoes while keeping pathways unfilled.
Convert all dimensions to feet before multiplying, or use consistent inches and divide by 1,728 for cubic feet.
Use the approved finished elevation, freeboard, liner, drainage and product plan for the exact bed; do not infer a universal rim gap from this volume calculation.
Compare one documented raised-bed fill scenario before procurement. Use approved inside geometry and fill depth, enter any deliberate top-up allowance, and copy the usable volume from the exact current package; run irregular shapes and layers separately.
