All tiny house tools
Every tool gives you a result the moment you open it, then updates as you change your inputs.
Where to start
Which tool should you use first?
The tools work best in roughly this order, because each answer feeds the next one.
Find your style
Not sure what kind of tiny house you want? The style quiz matches your land, budget and lifestyle to a style in eight questions.
Pick your size
The size calculator turns your household and habits into a square footage range and footprint.
Sketch the layout
Drag real-size furniture onto your footprint in the layout planner to check that everything fits.
Set a budget
The cost calculator prices your size, finishes and labor line by line.
Check weight and power
Building on wheels? Run the trailer weight calculator. Going off-grid? Size it with the solar calculator.

All the tools share the same assumptions, so the numbers agree with each other. The cost calculator uses the same per-square-foot figures you will find in our tiny house cost guide, and the size calculator compares your result with the 700 sq ft tiny house plans Tiny Homes Blueprint sells. They are planning tools, not quotes or engineering: once you know what you want, a complete plan set and local quotes turn the estimate into a real project.
Frequently Asked Questions
Are these tiny house tools really free?
Yes. All six tools are free to use with no account, email or payment. They run in your browser, and the layout planner saves your sketch only on your own device.
How accurate are the tiny house calculators?
They use typical 2026 US costs, material weights and space standards, so they are good for comparing options and setting a budget. Real costs and weights vary with your region, materials and design, so confirm with local quotes and a scale ticket before you commit.
Which tool should I use first?
If you are just starting, take the style quiz, then use the size calculator. With a style and size in hand, the cost calculator and layout planner give you much more useful results.
Can you turn my results into a plan?
Yes. Share your size, layout sketch and budget through the contact page, and Tiny Homes Blueprint can suggest one of our plans, quote a modification or discuss a custom design.
