Foot to Inch
Instantly convert foot to inch with fast, accurate, real-time results.
Feet and inches are both US customary units, but the two-unit format ("5 feet 11 inches") frequently needs to be collapsed into a single inch value — for clothing sizing, height comparisons, building specifications, and cut-list calculations in woodworking or construction. This page has the formula, a height reference chart, common construction measurements, and a full table from 1 to 20 feet.
Formula & Method
By definition, 1 foot = 12 inches exactly. This is a whole-number relationship — no decimals, no rounding required.
Example: 5.5 ft × 12 = 66 in
Converting feet and inches to total inches
For a height or measurement given as feet and inches (e.g., 5 ft 9 in), multiply the feet by 12 then add the remaining inches:
- Multiply feet × 12: 5 × 12 = 60 in
- Add remaining inches: 60 + 9 = 69 inches total
To go the other way (inches back to feet), divide by 12 — or use our inches to feet converter. To convert the total to metric, see our inches to meters converter.
Height Reference: Feet to Inches
Height in feet-and-inches is most usable in a single number (total inches) for medical records, clothing size charts, and statistical tables. Here's a quick reference from 4 ft to 7 ft:

Construction & Home Improvement
Builders, contractors, and DIY projects constantly toggle between feet and inches. Standard building materials and codes are often specified in feet, while actual measurements and cuts use inches:
| Feet | Inches | Standard building element |
|---|---|---|
| 1 ft | 12 in | One foot rule / tile reference |
| 2 ft | 24 in | Standard on-center stud spacing (2 ft OC) |
| 3 ft | 36 in | Counter/worktop height, door width (standard) |
| 4 ft | 48 in | Half-height of a standard drywall sheet |
| 6 ft 8 in | 80 in | Standard interior door height |
| 7 ft | 84 in | Common residential ceiling height |
| 8 ft | 96 in | Standard drywall sheet length / 8 ft ceiling |
| 9 ft | 108 in | Higher-spec residential ceiling (9 ft) |
| 10 ft | 120 in | Commercial/loft ceiling height |
| 12 ft | 144 in | One-story floor-to-floor height |
| 16 ft | 192 in | Standard stud wall height (2-story) |
Lumber and sheet goods
| Lumber length (ft) | Inches | Common use |
|---|---|---|
| 6 ft | 72 in | Fence pickets, short studs |
| 8 ft | 96 in | Standard stud, most framing lumber |
| 10 ft | 120 in | Longer framing, decking boards |
| 12 ft | 144 in | Long framing members, ridge boards |
| 16 ft | 192 in | Long span beams, sill plates |
Sports: Field & Court Dimensions
| Feet | Inches | Sports measurement |
|---|---|---|
| 3 ft | 36 in | Tennis net height at center |
| 4 ft | 48 in | Tennis net height at posts |
| 6 ft 6 in | 78 in | Men's volleyball net height |

Frequently Asked Questions
How many inches is 5 feet?
5 feet = 60 inches. Calculation: 5 × 12 = 60. This is one of the most common reference points — a person described as "5 feet tall" stands exactly 60 inches, or 1.524 meters.
How many inches is 6 feet?
6 feet = 72 inches (6 × 12 = 72). This equals 1.8288 meters. "6 feet" is frequently written as "6 ft" or "6'" — the prime symbol is the shorthand for feet, while the double-prime (") means inches.
How do I convert a mixed feet-and-inches measurement to inches?
Multiply the feet by 12 and add the remaining inches. Examples: 5 ft 6 in = (5 × 12) + 6 = 66 in; 6 ft 3 in = (6 × 12) + 3 = 75 in; 4 ft 11 in = (4 × 12) + 11 = 59 in.
How many feet is 60 inches?
60 inches ÷ 12 = 5 feet exactly. To convert any inch value back to feet, divide by 12. If there's a remainder, that becomes the inches: 65 in ÷ 12 = 5 ft remainder 5 → 5 ft 5 in. See our inches to feet converter for a full reverse table.
What is 5 ft 7 in in total inches?
5 ft 7 in = (5 × 12) + 7 = 60 + 7 = 67 inches. In metric: 67 × 0.0254 = 1.7018 m (roughly 170 cm). This height sits near the global average for men and is a common benchmark in medical BMI charts.
Why do builders use both feet and inches?
The US construction industry uses feet as a human-scale unit for large spans (room widths, ceiling heights, lot sizes) while inches capture fine detail (stud thickness, trim profiles, tile grout joints). The hybrid system persists because it's baked into every code book, product catalog, and trade school curriculum in the US — switching to metric would require re-specifying tens of millions of standard components. For practical calculations, converting all measurements to decimal inches first (and back at the end) avoids the mixed-unit arithmetic errors that cost carpenters material and time.
