Most shed plans come in a handful of fixed sizes: 8×8, 8×10, 10×12 and so on. If your yard actually fits a 9½ × 13-foot shed, you’re stuck adapting someone else’s drawings, recalculating every stud and rafter, and hoping the lumber math works out. FitMyShed takes a different approach. Instead of selling a set of PDFs, it generates a complete plan for the exact size and options you choose, then recalculates every cut, board and drawing to match.
We dug into FitMyShed’s free materials calculator, its published sample plan and its terms to see what you actually get for the money and who it’s best suited for.

What Is FitMyShed?
FitMyShed is a browser-based shed designer. You pick your roof style, dimensions, roof pitch, roofing, siding and snow load, and it produces a plan built specifically for that shed. Nothing is downloaded or shipped; you access everything online from a phone, tablet or computer, and every plan can be printed for the job site.
The key selling point is in the name: the plan fits your space rather than forcing your space to fit the plan. Measurements are calculated down to the 1/16 inch, and when you change any option, every number, cut and drawing is regenerated.
The Options You Can Customize
Both the free calculator and the paid designer work from the same set of inputs:
| Option | Choices |
|---|---|
| Roof style | Gable (peaked) or lean-to (single slope) |
| Width and depth | 4′ to 20′ each, in 6″ increments |
| Roof pitch | 2/12 through 12/12 |
| Roofing | Asphalt shingles or metal panels |
| Siding | LP SmartSide panels, T1-11 plywood, or board and batten |
| Snow load | None/light, moderate, or heavy |
| Doors and windows | Door placement and window options are set in the designer |
The snow setting matters more than it looks. FitMyShed sizes joists, rafters and headers using common span tables for the load you select, and frames everything at 16 inches on center. That’s a conservative approach, which is what you want from a plan you didn’t draw yourself.
The Free Materials Calculator
Before you spend anything, FitMyShed’s free calculator gives you a full materials list for your chosen size: lumber, floor/roof/siding sheets, foundation material, roofing, fasteners, connectors, door and window items and finishing supplies, each with an estimated price. Optional items are listed separately and left out of the required total.
A few details that show this tool was built by someone who has actually bought lumber:
- It counts store-length boards, not just cut pieces. The optimizer works with 8-, 10-, 12-, 14- and 16-foot stock (plus precut studs), packs the longest cuts first and allows 1/8 inch for saw kerf.
- It doesn’t pad every line with a blanket 10% waste factor. Shingles already include 10% waste and gravel includes a 15% compaction allowance, but lumber is calculated from the actual cutting plan. In FitMyShed’s 10×12 example, leftover offcuts come to about 5.4% of purchased board length.
- It’s honest about pricing. Prices are built-in 2025–26 U.S. estimates, not live store quotes, and they exclude labor, tools, permits, tax and delivery.
Even if you never buy the plans, the free list is a useful reality check before a trip to the lumberyard. For a broader all-in budget that includes labor and regional pricing, pair it with our shed cost calculator.
What the $37 Plan Includes
FitMyShed publishes part of a real plan for a 10′ × 12′ gable shed with a 6/12 roof, so you can see the output before buying. For that configuration, the plan estimates about $4,095 in materials, 120 square feet of floor space, 133 boards, 26 sheets and an overall height just under 12 feet.
The paid plan adds everything the free list leaves out:
- Complete cut list with the length and angle of every cut and what each piece is used for (skids, rim joists, headers, ridge board, barge rafters and so on). The 10×12 sample runs to about 46 lines.
- Board-by-board cutting plan showing which cuts come from which board, so you buy fewer boards and waste less.
- Sheet layouts for plywood and siding panels.
- Printable framing drawings for every wall and the floor, plus elevation views and a full-size rafter template.
- 16 step-by-step build stages shown in 3D, from site prep and skids through framing, roofing, siding, trim, doors and paint. You can rotate the model on your phone while you work.
- Unlimited designs. After checkout you can design as many sheds as you like and print any of them.

Who Should Buy FitMyShed?
A good fit if you:
- Have an odd-shaped or tight spot where a standard 8×10 or 10×12 doesn’t quite work.
- Are comfortable with a circular saw, drill and level and have a helper for wall raising.
- Want an accurate shopping list before you commit to a size.
- Learn better from 3D views than from 2D blueprints.
- Might build more than one structure, since one purchase covers unlimited designs.
Look elsewhere if you:
- Want a barn-style (gambrel) or saltbox roof.
- Need a building larger than 20′ × 20′. For bigger structures, see our pole barn cost calculator.
- Live somewhere that requires engineered or stamped drawings for your shed’s size.
- Would rather not build from scratch. A pre-cut kit may suit you better; see building your own shed with a kit.
A Note on Permits and Codes
FitMyShed is upfront that its plans follow common light-frame building practice for small, single-story outbuildings and are a guide, not engineered drawings. That’s normal for DIY shed plans, but it means you’re responsible for checking setbacks, snow and wind loads, foundation requirements and HOA rules. Some jurisdictions require a permit or stamped drawings above a certain size. Before you pick a final footprint, read our guide on whether you need a permit to build a shed, since staying under your town’s square-footage threshold can save you time and money.

Our Verdict
FitMyShed solves a real problem for DIY builders: getting a complete, accurate plan for the shed that fits your yard instead of the closest stock size. The free materials calculator is genuinely useful on its own, and the $37 plan adds the parts that save the most time on a build: a waste-reducing cutting plan, framing drawings for every wall, and a 3D walkthrough you can follow step by step. With a 60-day money-back guarantee, the risk is low.
Its limits are clear and stated up front: gable and lean-to roofs only, nothing over 20 feet, and no engineered drawings. If those work for your project, FitMyShed is one of the more practical ways to plan a custom shed.
