Plank width is often chosen from a mood board and confirmed late, after construction, grade and color are already settled. That order causes problems. Width affects how the room reads, which construction is appropriate, how much the material costs and how the floor behaves as indoor conditions change. Choosing it early, and for the right reasons, saves a round of re-quoting.
This guide explains what face width does to a space, lists the widths we run at Vu Uy Wood, and shows how width connects to construction and length.
What face width does to a room
Face width is the visible width of the board once it is installed, not including the tongue. It sets the visual scale of the floor.
Wider boards show more of the grain on each board and create a calmer rhythm. With fewer long-side joints across the room, the floor reads as a broad surface rather than a pattern of lines. Wide planks suit large open areas, high ceilings and interiors where the oak itself is the main material.
Narrower boards suit tighter spaces and can be more economical. More joints across the room give a finer, busier texture that keeps small rooms in proportion. Narrow widths are also the traditional choice in many classic interiors and for pattern floors.
A few practical points follow from this:
- In a small room, very wide boards can make the floor look like a few large panels rather than a wood floor.
- In a large open-plan area, narrow boards produce a dense field of lines that can feel busy.
- Grade and width work together. A wide board shows more of its character on each piece, so knots and color movement are more visible per board in a Rustic or Natural grade.
Widths in production and to order
We separate widths into two groups. Widths in current production are sizes we have already run. Widths to order can be made on request. Other widths can be discussed against a specification.
| Width (imperial) | Width (metric) | Status |
|---|---|---|
| 3” | 76mm | To order |
| 3-1/4” | 83mm | In production |
| 3-1/2” | 89mm | In production |
| 4” | 102mm | To order |
| 5” | 127mm | In production |
| 5-1/2” | 140mm | To order |
| 6” | 152mm | In production |
| 7” | 178mm | To order |
| 7-1/2” | 190mm | In production |
| 8” | 203mm | To order |
| 9” | 229mm | In production |
| 9-1/4” | 235mm | In production |
| 10” | 254mm | To order |
| 11” | 280mm | To order |
| 12” | 305mm | To order |
The full range runs from 3” (76mm) to 12” (305mm). If the width you need is not listed, include it in your specification and we will review it.
How width relates to construction
Width is not an independent choice. The wider the board, the more it can move across its width as indoor humidity changes, because wood shrinks and swells mostly across the grain rather than along it. The construction of the board is how that movement is managed.
| Construction | Build | Width guidance |
|---|---|---|
| Solid | One piece of oak through the full thickness, no core | Best suited to narrower boards and to projects where repeated sanding and refinishing is a priority |
| 2-layer engineered | Sawn oak wear layer bonded to a stable plywood core | A practical choice where overall floor height is limited; commonly used for herringbone and chevron |
| 3-layer engineered | Wear layer over a cross-layered core with a backing layer | Well suited to wider boards and larger open areas where dimensional stability matters |
In practice:
- Planning wide planks for an open-plan project? Start the conversation with 3-layer engineered construction.
- Want solid oak? Keep the width toward the narrower end of the range.
- Pattern floor with limited floor height? 2-layer engineered is the usual starting point.
Current standard builds are 5/8” (15mm) overall with a 3mm sawn wear layer and 3/4” (20mm) overall with a 6mm sawn wear layer. Other thicknesses from 3/8” (10mm) to 13/16” (21mm) can be made to order. For a deeper comparison of constructions, see 2-layer vs 3-layer engineered oak and solid vs engineered hardwood flooring.
Width and cost
Width has a cost effect that is easy to overlook. A wide board needs wide clear face material, and the wider the face, the harder it is to find that material without defects for a given grade. That is part of the reason narrower boards can be more economical. When budget matters, compare quotes at two widths as well as two grades: sometimes stepping down one width achieves the saving without changing the look of the grade.
Random length or fixed length
Length is the other half of the board’s proportion, and it should be chosen alongside width.
- Random length runs from 12” to 86” (300 to 2200mm). This is the normal choice for a straight-lay plank floor. Mixed lengths stagger the end joints naturally and use the timber efficiently.
- Fixed length and long board up to 118” (3000mm) are cut to order. Fixed length suits designs where end joints should line up or follow a set pattern. Long boards emphasize the length of a room and pair well with wide faces.
A wide board in short lengths can look stubby. A wide board in long lengths gives the calm, continuous surface that most wide-plank projects are aiming for. Keep this in mind when you ask for a quotation: the length mix affects both appearance and yield.
More than one width in one order
Projects often need more than one board size, for example a wide plank in living areas and a narrower board or herringbone in a hallway. We make to specification rather than from finished stock, and one order can include more than one format or board size while staying within the same approved color standard. State each width and its quantity separately in the RFQ so each can be sampled and priced.
Checklist: deciding plank width
- What is the size and shape of the main rooms? Large open areas and narrow rooms point in different directions.
- Which construction will you use, and does it suit the width? Wide boards point toward 3-layer; solid points toward narrower widths.
- Is the width in current production, or to order?
- Random length or fixed length? If fixed, what length?
- Which grade? Wider boards show more character per board.
- Does the project need more than one width under the same color?
- Has the width been seen on a finished sample, not only in a photo?
Working with Vu Uy Wood
We manufacture solid and engineered French White Oak flooring in widths from 3” (76mm) to 12” (305mm), with seven widths in current production and others made to order. Random length runs from 12” to 86” (300 to 2200mm), with fixed length and long board to 118” (3000mm) cut to order. You can see how different widths look installed on our completed work page. To set width together with construction, grade and color, use the Specify page, which turns your choices into a written brief we can quote.
