How to use the calculator
Select the required conversion direction and enter the known value. Choose a building preset or enter custom floor heights. Add special levels only when they affect the estimate.
Review the live preview before submitting the completed form. The result separates full stories from any partial story. Export the final calculation for records or project discussions.

Frequently asked questions
How many feet equal one story?
One story often measures between nine and fourteen feet. Actual height depends on structure, services, and building use. Use measured floor-to-floor dimensions whenever accurate plans are available.
Why is a story estimate not exact?
Buildings use different ceiling heights and structural systems. Ground floors are often taller than upper floors. Mechanical levels and roof structures also change total height.
What is floor-to-floor height?
Floor-to-floor height measures between finished floor levels. It includes ceilings, services, slabs, and structural depth. This value is best for estimating building stories.
Can I enter feet and inches?
Yes, select feet and use the additional inches field. The calculator converts inches into a decimal-foot amount. This supports measurements copied directly from building records.
Does the calculator support metres?
Yes, metres and centimetres are supported input units. They are converted internally into feet before calculation. Results also display the equivalent measurement in metres.
How are basements handled?
Basement height can be separated from above-ground stories. Enter the basement count and typical basement height. Disable extra levels when they should remain included.
What is a partial story?
A partial story is the remaining fraction after full floors. The calculator reports that fraction as a percentage. It does not confirm legal classification under building codes.
Which preset should I choose?
Select the preset closest to the building use. Then replace its heights with known project measurements. Custom settings provide the most flexible estimating approach.
Can the calculator work backwards?
Yes, choose stories to total feet mode. Enter whole or decimal stories and structural details. The result estimates overall height using those assumptions.
What does round up mean?
Round up returns the next complete whole story. It may overstate physically completed floor area. Use exact results for planning and comparison work.
Can this replace architectural drawings?
No, this tool provides an early planning estimate. Final dimensions require verified drawings and professional review. Local codes may define stories using different rules.
