Shed Material Estimator
Planning a shed build is much easier when you have a good idea of the materials you'll need before you start.
A shed material estimator can help you work out approximate quantities for the major parts of your project based on the size and design of your shed.
Whether you're planning a small backyard storage shed or a larger workshop, estimating your materials early can help you organize your project, compare different shed sizes, and prepare a better shopping list.

Why Use a Shed Material Estimator?
A shed project involves more than just buying some timber and roofing. You'll need to consider floor framing, wall framing, sheathing, siding, roofing, doors, windows, and the foundation.
Using an estimator gives you a practical starting point before purchasing materials. You can also change the dimensions and design options to see how they affect the estimated quantities.
This can be particularly useful when you're deciding between different shed sizes or comparing a gable roof with a lean-to design.
Estimate Materials for Your Shed
Our Shed Material Estimator Calculator lets you enter the basic details of your planned shed and receive an approximate material estimate.
You can enter
Shed length and width
Wall height
Framing spacing
Foundation type
Roof style
Roof pitch
Number and size of doors
Number and size of windows
The calculator then provides estimated quantities for important materials, including floor joists, plywood, wall studs, wall plates, siding, roof rafters, roof sheathing, roofing coverage, door and window framing, and foundation materials.
Know exactly what you’re building. CAD drawings give you the EXACT proportions and dimensions so you’re not relying on inaccurate or poorly drawn plans.
