Free Inches to Feet Converter
Published: 14 November 2026 · Updated: 14 November 2026
Type a length in inches and the value in feet appears instantly, together with the feet-and-inches breakdown used for heights and room sizes. The converter works both ways, so feet convert back to inches too. It starts with 72 inches, which is 6 feet (6 ft 0 in). For heights in metric, use the Free Inches to Cm Converter.
1 foot is exactly 12 inches, so divide any inch value by 12. That makes 72 inches exactly 6 feet, and 66 inches 5 ft 6 in — the breakdown line shows the whole feet plus the inches left over, the way heights are spoken in the UK and US.

What is an inch?
An inch (in) is a unit of length in the imperial and US customary systems, equal to exactly 25.4 millimetres. It is the smallest step on most tape measures, divided into halves, quarters, eighths and sixteenths.
Inches are used for screen sizes, wheel diameters, pipe fittings and heights in the United States, and remain common in the United Kingdom. Twelve inches make one foot.
What is a foot?
A foot (ft) is an imperial and US customary unit of length equal to exactly 12 inches, or 30.48 cm. Three feet make one yard.
Feet are the standard unit for heights of people, ceilings, doors and fences in the United States, and are still used for heights and property in the United Kingdom. A height is usually spoken as feet and inches together — 5 ft 9 in — rather than as a decimal number of feet.
How to use this converter
- Type your length in the inches box — feet appear as you type, with the feet-and-inches breakdown underneath.
- Decimals work: 66.5 in becomes 5.5417 ft, or 5 ft 6.5 in.
- To convert back, type in the feet box or press Swap direction, which flips the converter and carries the converted value over.
- The result line also shows the reverse rate: 1 ft = 12 in.
Inches to feet formula
Let Lin be the length in inches and Lft be the same length in feet:
- Feet from inches: Lft = Lin ÷ 12
- Inches from feet: Lin = Lft × 12
- Feet-and-inches breakdown: whole feet = Lin ÷ 12 rounded down, and the inches left over = Lin − (whole feet × 12)
The number 12 is exact: a foot is defined as 12 inches. For the wider story, see our metric vs imperial conversion guide for Europe.
Worked example
A wall measures 138 inches long, and the flooring is sold by the foot:
- Divide by 12: 138 ÷ 12 = 11.5 ft
- Break it down: 11 × 12 = 132, and 138 − 132 = 6, so 138 in = 11 ft 6 in
- Check: 11.5 × 12 = 138 in, back where we started
So the wall is 11 ft 6 in long — order flooring for 11.5 feet. Try 138 in the converter above.

Everyday benchmarks: inch lengths in feet
These inch lengths come up in homes, shops and sport — here they are in feet:
- Interior door — 80 in = 6 ft 8 in. The standard US interior door height.
- Ceiling height — 96 in = 8 ft. The usual ceiling in older US homes; newer rooms are often 9 ft (108 in).
- Kitchen counter — 36 in = 3 ft. Standard counter height, exactly 3 feet.
- Basketball hoop — 120 in = 10 ft. The rim sits 10 feet above the court.
- Fence panel — 72 in = 6 ft. The common privacy-fence height.
- Adult height — 66 in = 5 ft 6 in. A common height, spoken as feet and inches, not 5.5 ft.
- Sofa length — 84 in = 7 ft. A three-seater sofa is often around 7 feet long.

Frequently asked questions
How do you convert inches to feet?
Divide the inch value by 12. For example, 48 in ÷ 12 = 4 ft. A foot is defined as exactly 12 inches, so the conversion is exact.
What is 72 inches in feet?
72 inches is exactly 6 feet. Divide by 12: 72 ÷ 12 = 6, with nothing left over — so the feet-and-inches breakdown is 6 ft 0 in.
What is 66 inches in feet and inches?
66 inches is 5 ft 6 in. Dividing 66 by 12 gives 5 whole feet (60 inches), leaving 6 inches over. As a decimal that is 5.5 ft.
How many inches are in a foot?
There are exactly 12 inches in a foot. This has been the definition since the imperial system was standardised, and it is also true in US customary units.
What is 100 inches in feet?
100 inches is 8.3333 feet, which is 8 ft 4 in. Dividing 100 by 12 gives 8 whole feet (96 inches), leaving 4 inches over.
How do I convert feet back to inches?
Multiply the feet by 12. For example, 5 ft × 12 = 60 in. Type in the feet box here, or press Swap direction to flip the converter.
Why do heights use feet and inches together?
Saying 5 ft 9 in is easier to picture than 5.75 ft, and it matches how tape measures are marked — whole feet, then inches. The breakdown line on this converter gives both forms so you can use whichever suits.
What is 1 inch in feet?
1 inch is 1/12 of a foot, which is 0.0833 ft to four decimal places. One inch is the smallest whole step on an imperial tape measure.
