The Feet To Stories Calculator helps estimate how many floors or stories a building has based on its height in feet. This is commonly used in construction, architecture, real estate, and city planning. By using average story height values for residential and commercial buildings, the calculator quickly converts vertical measurements into understandable building levels. It's especially helpful when comparing building sizes or analyzing zoning and height limits in urban projects.
formula of Feet To Stories Calculator
Stories = Feet / Average Story Height
Where:
Feet = total height of the structure in feet
Average Story Height = estimated height of one story in feet
Typical average story heights:
Residential buildings: 10 feet per story
Commercial buildings: 12 to 15 feet per story
Standard formulas:
Stories (Residential) = Feet / 10
Stories (Commercial) = Feet / 12 or Feet / 15
Depending on building type and design, the average height can vary, but these figures offer a solid general estimate.
Table: Feet to Stories Conversion Chart
| Total Height (Feet) | Stories (Residential, 10 ft/story) | Stories (Commercial, 12 ft/story) | Stories (Commercial, 15 ft/story) |
|---|---|---|---|
| 30 | 3 | 2.5 | 2 |
| 60 | 6 | 5 | 4 |
| 90 | 9 | 7.5 | 6 |
| 150 | 15 | 12.5 | 10 |
| 300 | 30 | 25 | 20 |
This table gives a quick reference for estimating the number of stories from a known building height.
Example of Feet To Stories Calculator
Suppose a building is 180 feet tall. To estimate how many stories it has:
For a residential structure:
Stories = 180 / 10
Stories = 18
For a commercial structure (average 12 ft/story):
Stories = 180 / 12
Stories = 15
For taller commercial stories (15 ft/story):
Stories = 180 / 15
Stories = 12
So depending on the type, the building could have 12 to 18 stories.
Most Common FAQs
It's a helpful estimate. Exact story counts can vary based on ceiling height, mechanical floors, or architectural design. Always verify with floor plans for precise numbers.
If the building’s purpose is unclear, using 12 feet per story is a safe general estimate. It balances between residential and smaller-scale commercial structures.
Yes, it’s often used in those areas to provide quick and reasonably accurate floor estimates when detailed architectural data is unavailable.
