| Units of Measure |
| The following page details wood measurement techniques used generally in the timber trade and here at Richard Potter Timber. |
| |
| Softwood |
| The great majority of imported softwoods are sold in metric lengths based on multiples of 0.3 of a metre (300mm). There follows a basic list of available metric lengths together with the approximate imperial equivalents. The packs of timber we stock are mostly bought on a random length basis and do not necessarily contain every length. |
| |
| 0.6 Metres | 1´11.5" | 3.0 Metres | 9´10" |
| 0.9 Metres | 2´11" | 3.3 Metres | 10´9.5" |
| 1.2 Metres | 3´11" | 3.6 Metres | 11´9.5" |
| 1.5 Metres | 4´11" | 3.9 Metres | 12´9" |
| 1.8 Metres | 5´10.5" | 4.2 Metres | 13´9" |
| 2.1 Metres | 6´10.5" | 4.5 Metres | 14´8" |
| 2.4 Metres | 7´10.5" | 4.8 Metres | 15´8" |
| 2.7 Metres | 8´10" | 5.1 Metres | 16´8" |
When considering timber purchases customers are advised to ask for actual lengths required. The purchase of longer lengths often results in paying for unnecessary waste. |

| |
| Hardwood |
| The International Hardwood Trade has not yet fully converted to the Metric System. The Imperial (Feet & Inches) system of measurement is still sometimes used. Richard Potter always adheres to Trading Standards and invoices in Metric as required. Clients should note that Hardwoods are largely supplied on a random width and length basis. Our staff will be pleased to advise on specific size availability. |
| |
| Sheet Materials |
| Plywood manufacturers world wide produce sheet sizes which are always imperial lengths and widths. The vast majority of sheets are always 8´x4´ (2440mm x 1220mm). The thicknesses, however, are always in millimetres. |

| Door and Frame Sizes |
| The table below details available door and frame sizes both in Metric and Imperial measurements. |
