Shed Floor Framing: Joist Layout, Spacing & Span Calculations

Straight Walls with Doors & Windows
Frame any shed wall with precise stud placement, king studs, jack studs, headers, and cripples automatically calculated around any opening.
Rake Walls for Gable Ends
Set your roof pitch and let the rake wall builder calculate every stud length and bevel angle automatically. No manual trigonometry needed.

Shed Plan FAQ
How do I create a shed floor plan?
Open the Floor Plan Builder, enter your shed's width and length, select your floor joist size (2x6, 2x8, or 2x10) and spacing, and the tool generates a complete joist layout with a cut list. You can then export it as a blueprint PDF.
What size lumber should I use for shed floor joists?
For most sheds, 2x6 joists work well for spans up to 8 feet, 2x8 joists for spans up to 12 feet, and 2x10 joists for larger spans. The Floor Plan Builder flags undersized joists automatically based on your span and spacing.
Can I design a 12x16 shed plan with this tool?
Yes. Enter 12' x 16' as your shed dimensions and the tool builds out a full floor framing plan, wall layouts for all four sides, and a roof framing plan — any size works.
Does the tool generate a cut list for my shed?
Yes. Every floor plan, wall, and roof section generates a full cut list including part names, quantities, lengths, and cut angles. Export it as a PDF or print it directly.
Can I design a lean-to or single-slope shed roof?
Yes. The Single-Slope Roof Builder handles lean-to and shed roofs. Set your wall heights and pitch to get exact rafter lengths, bird's mouth cuts, and overhang dimensions.
