Product dimensions describe measurements along different directions, but the order is not universal. A listing may use length × width × height (L × W × H), width × depth × height, or another convention. Follow the labels in the listing or manufacturer's drawing; do not infer the order from three numbers alone.
- Length: often the longer horizontal dimension of an item, though usage depends on the product.
- Width: the side-to-side dimension across the face or shorter horizontal span.
- Height: the vertical distance from bottom to top.
- Depth: how far an item extends front to back; on some products it may be used where another source says width.
| If a labeled listing says… | Read it as… |
|---|---|
| L × W × H = 18 × 12 × 4 in | 18 in long, 12 in wide, 4 in high |
| W × D × H = 18 × 12 × 30 in | 18 in wide, 12 in deep, 30 in high |
These are examples of how labels work, not dimensions for a particular product. Confirm whether the measurements include handles, feet, trim, packaging, or other protruding parts.
