Common whole-inch measurements

Measurements from 12 to 24 inches

Measurements in this range are common for shelves, monitors, cabinets, picture frames, boxes, tools, and household products.

Measurements from 30 to 96 inches

Larger inch values frequently describe furniture, doors, tables, beds, televisions, shelving, and room features.

Common screen measurements

Screen sizes are usually measured diagonally. The converted centimeter value also describes the diagonal, not the width.

• 13.3 inches = 33.782 centimeters;
• 14 inches = 35.56 centimeters;
• 15.6 inches = 39.624 centimeters;
• 24 inches = 60.96 centimeters;
• 27 inches = 68.58 centimeters;
• 32 inches = 81.28 centimeters;
• 55 inches = 139.7 centimeters;
• 65 inches = 165.1 centimeters.

Width and height depend on the display's aspect ratio and must be checked separately.

Common picture and frame measurements

Rectangular sizes contain two measurements. Convert both dimensions separately.

A frame's listed size may refer to its opening rather than its complete outside dimensions.

Common furniture measurements

Furniture descriptions may show width, depth, height, or length. Keep the labels beside each number when converting.

• 18 inches = 45.72 centimeters;
• 24 inches = 60.96 centimeters;
• 30 inches = 76.2 centimeters;
• 36 inches = 91.44 centimeters;
• 48 inches = 121.92 centimeters;
• 60 inches = 152.4 centimeters;
• 72 inches = 182.88 centimeters;
• 84 inches = 213.36 centimeters.

Product dimensions alone may not include the clearance required for doors, drawers, chairs, reclining mechanisms, or walking space.

Common fractional measurements

Small measurements may be easier to express in millimeters. For example, 1/4 inch equals 6.35 millimeters.

How to calculate a value not listed

A reference list cannot contain every possible measurement. To calculate another value, multiply it by 2.54.

Example: convert 47 inches

Example: convert 62.5 inches

Exact conversions and rounded product sizes

A mathematical conversion may differ slightly from a rounded commercial label. For example, 4 x 6 inches equals exactly 10.16 x 15.24 centimeters, but a similar product may be labeled 10 x 15 centimeters.

Rounded labels can be convenient, but they should not be assumed to describe identical dimensions. Check the actual specifications when fit or compatibility matters.

Common mistakes

Using a nearby chart value

If the required measurement is 17.5 inches, do not substitute the conversion for 17 or 18 inches.

Confusing diagonal and rectangular dimensions

Screen size usually describes a diagonal, while furniture and frame sizes often describe separate width and height measurements.

Ignoring fractional or decimal portions

The difference between 10 inches and 10.5 inches is 1.27 centimeters.

Assuming rounded metric labels are exact conversions

Convenient product labels may differ from the exact calculated dimensions.
