Frame decks, sheds & homes - and see them in 3D
DIYerBench is a free framing calculator for DIYers and owner-builders. Turn plain measurements into code-aware stud and joist layouts, an interactive 3D model, and a ready-to-shop material list.
What is DIYerBench?
DIYerBench is a free online framing calculator and 3D design tool for DIY builders. It turns simple measurements into code-referenced framing plans - sizing joists, studs, beams, headers, posts and plates - then shows the structure as an interactive 3D model and lists the lumber you need to build it.
It's built for weekend builders, owner-builders and pros who want a fast, visual estimate without wrestling a spreadsheet or CAD program.

Why DIYers choose DIYerBench
Code-aware sizing
Member sizes follow DCA 6 and IRC R507 prescriptive tables, and the app refuses to guess when a design falls outside them.
Instant 3D model
Every layout is drawn as an interactive 3D frame you can orbit, explode and toggle by layer.
Material & cut lists
Decks come with a stock-optimized bill of materials, rough costs and retailer search links.
Imperial & metric
Switch units anywhere; layouts read in feet or centimetres without re-entering anything.

Frequently asked questions
Is DIYerBench free?
Yes. Every calculator is completely free to use, with no signup and no account required. It runs entirely in your web browser.
What can I build with DIYerBench?
Today you can fully frame a deck (joists, beams, posts, footings and a material list), lay out a stud wall, and sketch a floor plan that generates a 3D wall-framing model - useful for sheds, garages and room additions. Guided shed and whole-home workflows are on the roadmap.
Do I need to install anything?
No. DIYerBench is a browser-based web app. There is nothing to download or install, and it works on phones, tablets and computers.
Is DIYerBench accurate enough to build from?
DIYerBench uses recognized prescriptive methods (AWC DCA 6 and IRC R507) to size members, but it is a planning and estimating aid - not stamped engineering. Always verify sizing against your local building code and a licensed professional, and get the required permit before building.
Does it support metric units?
Yes. You can switch between imperial and metric at any time; lengths and stud-center positions display in feet or centimetres.
What is a stud-center schedule?
It is a list of the centre position of every stud measured from the start of the wall, in feet or centimetres - exactly what you need to mark out plates before nailing up a wall.
Can I see my design in 3D?
Yes. Every deck, wall and floor plan is rendered as an interactive 3D model you can rotate, zoom, explode and filter by component.
Does DIYerBench work on mobile?
Yes. It is mobile-first and designed to be used on a phone on the job site as well as on a desktop.
