Construction & DIY Tools
CraftFrame construction tools are free, practical calculators built to help DIY builders plan foundations, spacing, and concrete work correctly before construction begins.
These tools are designed for real-world projects — not generic estimates — and help reduce costly mistakes when building sheds, fences, decks, and other outdoor structures.
All calculators are browser-based, fast to use, and require no registration.
Free Construction Calculators for DIY Builders
This page includes a growing collection of free construction calculators created specifically for DIY and small-scale outdoor building projects.
Use these tools to:
- calculate post hole depth before digging
- estimate concrete volume for footings, slabs, and piles
- determine correct fence post spacing
- choose the right foundation type for a shed or small structure
Each calculator is based on practical building logic commonly used in real construction — not simplified online formulas that ignore ground conditions, load paths, or spacing rules.
DIY Tools for Sheds, Fences, Decks & Outdoor Structures
These tools are ideal for homeowners and DIY builders working on:
- garden sheds and storage buildings
- fences and fence posts
- decks, pergolas, and small outdoor frames
- concrete pads, slabs, and footing systems
Instead of guessing measurements or relying on incomplete tutorials, you can use these calculators to plan dimensions and quantities before cutting materials or pouring concrete.
Why Use CraftFrame Construction Tools?
CraftFrame tools are created by engineers and experienced builders who understand common DIY mistakes.
Unlike generic calculators, these tools:
- focus on real construction use cases
- provide realistic depth, spacing, and volume guidance
- help prevent over-pouring concrete or under-sizing foundations
- support better planning before buying materials
They are designed to complement detailed DIY plans, but can also be used independently for early-stage planning.
