Door Height Chart: Standard Heights in Inches & Cm

How tall should a door be?

Door height is measured in inches in the US and in centimetres everywhere else — 1 inch = 2.54 cm exactly. Doors are sold in standard heights: 80 inches (6 feet 8 inches) is the most common interior and exterior door height, 84 inches (7 feet) is the common taller and garage-door height, and 96 inches (8 feet) is the grand-entry and double-door height, with 60–72 inches for access and closet doors and 108 inches for custom extra-tall entries. The door types, by height: attic / crawlspace access 60–66 inches; closet / bifold 66–72 inches; short interior 76–78 inches; standard interior 80–82 inches; standard exterior 80–84 inches; tall interior 82–86 inches; tall exterior 84–90 inches; french / patio 80–90 inches; standard garage 84–96 inches; barn 84–96 inches; double / grand entry 90–96 inches; custom / extra-tall 96–108 inches.

Two things about the model are worth stating plainly. First, the height in centimetres is the height in inches times 2.54 — 80 × 2.54 = 203.20 cm. Second, the matching types are every door type whose height range contains your height — at 80 inches that is three types: standard interior, standard exterior, french / patio; all listed in Accuracy & limitations.

The door height chart

Five heights appear more than once in the chart — 66 inches is shared by attic / crawlspace access and closet / bifold, 82 inches is shared by standard interior, standard exterior, tall interior and french / patio, 84 inches is shared by standard exterior, tall interior, tall exterior, french / patio, standard garage and barn, 90 inches is shared by tall exterior, french / patio, standard garage, barn and double / grand entry, and 96 inches is shared by standard garage, barn, double / grand entry and custom / extra-tall. The shortest standard height is the 60-inch attic / crawlspace access at 152.40 cm, and the longest is the 108-inch custom / extra-tall at 274.32 cm.

The worked example, line by line

Setup: 80-inch height.

Line 1 — the height in centimetres. The height in centimetres is 80 × 2.54 = 203.20 cm.

Line 2 — the matching types. The door types whose height range contains 80 inches are standard interior, standard exterior, french / patio — three types.

Line 3 — the switch from a standard interior door to a custom entry. Switching from an 80-inch standard interior door to a 108-inch custom entry adds 28 inches — 71.12 cm.

Line 4 — the check. 80 × 2.54 = 203.20 cm, the height; and 108 − 80 = 28 inches, the extra height.

The reverses, worked backwards

Smallest height (to the hundredth) for the centimetre figure to reach 200.00 cm: At the displayed 78.75 in the figures are Height 78.75 in; 200.03 cm (unrounded 200.0250 cm); matching types: no matching type. At the displayed 78.75 in the height is 200.03 cm (unrounded 200.0250 cm). At 78.74 in the figure is 199.9996 cm — below 200.00 cm — so 78.75 in is the smallest height (to the hundredth) for the centimetre figure to reach 200.00 cm.

Largest height (to the hundredth) for the centimetre figure to STAY at or below 250.00 cm: At the displayed 98.42 in the figures are Height 98.42 in; 249.99 cm (unrounded 249.9868 cm); matching types: custom / extra-tall. At the displayed 98.42 in the height is 249.99 cm. At 98.43 in the figure is 250.01 cm — above 250.00 cm — so 98.42 in is the largest height (to the hundredth) for the centimetre figure to stay at or below 250.00 cm.

Smallest height (to the hundredth) for the centimetre figure to reach 275.00 cm: At the displayed 108.27 in the figures are Height 108.27 in; 275.01 cm (unrounded 275.0058 cm); matching types: no matching type. At the displayed 108.27 in the height is 275.01 cm (unrounded 275.0058 cm). At 108.26 in the figure is 274.98 cm — below 275.00 cm — so 108.27 in is the smallest height (to the hundredth) for the centimetre figure to reach 275.00 cm.

Smallest height (to the hundredth) to match standard interior: At the displayed 80.00 in the figures are Height 80 in; 203.20 cm; matching types: standard interior, standard exterior, french / patio. At the displayed 80.00 in the height is 203.20 cm and it matches standard interior. At 79.99 in the figure is 203.17 cm and it does not match standard interior — it matches nothing — so 80.00 in is the smallest height (to the hundredth) to match standard interior.

Largest height (to the hundredth) to still match closet / bifold: At the displayed 72.00 in the figures are Height 72 in; 182.88 cm; matching types: closet / bifold. At the displayed 72.00 in the height is 182.88 cm and it matches closet / bifold. At 72.01 in the figure is 182.91 cm and it no longer matches closet / bifold — it matches nothing — so 72.00 in is the largest height (to the hundredth) to still match closet / bifold.

Smallest height (to the hundredth) to match double / grand entry: At the displayed 90.00 in the figures are Height 90 in; 228.60 cm; matching types: tall exterior, french / patio, standard garage, barn, double / grand entry. At the displayed 90.00 in the height is 228.60 cm and it matches double / grand entry. At 89.99 in the figure is 228.57 cm and it does not match double / grand entry — it still matches tall exterior, french / patio, standard garage, barn — so 90.00 in is the smallest height (to the hundredth) to match double / grand entry.

With Height 96 in, Height 96 in; 243.84 cm; matching types: standard garage, barn, double / grand entry, custom / extra-tall. With Height 47.24 in, Height 47.24 in; 119.99 cm (unrounded 119.9896 cm); matching types: no matching type. With Centimetre bars, 72 in = 182.88 cm; 80 in = 203.20 cm; 96 in = 243.84 cm.

A note on the rounding: at 78.74 inches the unrounded centimetre figure is 199.9996 cm, which rounds half-up to 200.00 cm; at 118.11 inches the unrounded centimetre figure is 299.9994 cm, which rounds to 300.00 cm; at 47.24 inches the unrounded centimetre figure is 119.9896 cm, which rounds to 119.99 cm. The page prints the unrounded values so the rounding does not mislead you. A negative height input is floored at 0 — it shows 0.00 cm and no matching type, never a negative number.

Who uses this

• The homeowner buying a standard interior door: they learn an 80-inch door is 203.20 cm and matches standard interior, standard exterior, french / patio — and they check the 80.00 in reverse to see the smallest height that matches standard interior.
• The homeowner fitting a tall entry: they learn a 96-inch door is 243.84 cm and matches standard garage, barn, double / grand entry and custom / extra-tall — and they check the 90.00 in reverse to see the smallest height that matches double / grand entry.
• The homeowner with a 66-inch closet: they learn it is 167.64 cm and matches attic / crawlspace access and closet / bifold — and they check the 72.00 in reverse to see the largest height that still matches closet / bifold.
• The homeowner with a 47.24-inch measurement: they learn it is 119.99 cm — the unrounded figure is 119.9896 cm — and it matches nothing, so they check the 78.75 in reverse to see the smallest height for the centimetre figure to reach 200.00 cm.

Accuracy & limitations

The math is first-principles: the height in centimetres is the height in inches times 2.54, rounded to two decimals half-up; the matching types are the door types whose height range contains your height; the height in inches is floored at 0 — a negative height input shows 0.00 cm and no matching type, never a negative number. The reverses are judged on the UNROUNDED centimetre figure: at 108.27 in the height is 275.0058 cm unrounded, which rounds to 275.01 cm, so it reaches the 275.00 cm target; at 108.26 in the height is 274.9804 cm unrounded, which rounds to 274.98 cm, so it does not. What the model cannot do is set your door height: the heights in the table are the standard figures, not a rule for every opening — when a supplier quotes a height in centimetres, the finished door is usually a centimetre or two short after trimming, not exactly the quoted height; a door that is too tall drags and binds; a door that is too short leaves a gap that leaks air and light; and an 8-foot door in a standard-height room looks out of proportion and costs far more than a standard 80-inch door. Measure from the finished floor to the top of the opening — not from the subfloor — and remember the rough opening is about 2 inches taller than the door slab to allow shimming and levelling. Use it to find the centimetre figure and the matching door types for your height — then measure twice before you buy.
