Summary

Herringbone and straight lay are the two patterns that come up on almost every wood, laminate and LVT flooring quote. Straight lay (planks running parallel, usually along the longest wall or towards the main light source) is the volume product: fast to fit, low wastage, forgiving of a slightly out-of-square room. Herringbone (short blocks laid at 90° to each other in a zig-zag) is the premium finish customers see in magazines and ask for by name — and it is routinely under-priced by fitters who quote it as "a bit more than planks".

The pattern changes almost every variable on the job: the product you can use (blocks or purpose-made herringbone planks, not standard boards), the installation method (bonded, not floated, for timber), the setting-out time, the cutting waste at every perimeter, the skill level required, and the time on your knees. It also changes what happens if the room is out of square, because a herringbone field makes any error visible along every wall rather than just the last row.

This guide puts the two side by side so you can quote accurately, explain the premium to the customer, and pick the right pattern for the room.

Detailed Guidance

Why herringbone costs what it costs

Customers often assume the premium is all in the materials. In practice the labour premium is larger. A straight lay is a production job: you set a first row, then run full boards across the room, cutting one piece per row at the far wall and using the offcut to start the next. A herringbone field has a cut at every wall on every single row, on both sides, and each of those cuts is at 45° to the block. On a 20m² room with 90 × 400mm blocks you are handling 550+ individual pieces instead of 60–80 planks, each bedded, tapped tight on two faces and checked for alignment.

Then there is setting out. A herringbone pattern that drifts by 2mm over the first metre will be out by 10mm by the far wall, and that error shows as the "arrow" veering off-line down the room. Experienced fitters allow a couple of hours to find the room's true centreline, dry-lay the first chase and square it off before any adhesive is opened. None of this is optional and none of it is visible to the customer, so it needs to be explained on the quote.

Measuring and ordering

Measure the net floor area, then apply the wastage factor to the pattern, not the product:

Room shape Straight lay Herringbone Chevron / double herringbone
Simple rectangle +5% +10% +12%
L-shape or through-room +7% +12% +15%
Bays, alcoves, diagonal walls +8–10% +15% +18%

Order from one batch where possible; herringbone shows shade variation more than straight lay because adjacent blocks run in opposite grain directions and catch the light differently. Check the product has left- and right-hand blocks (most engineered herringbone is sold as A and B packs, typically half and half) — the pattern cannot be laid from one hand only.

Subfloor preparation

Both patterns need the same moisture discipline — hygrometer test to ≤75% RH on screeds, surface DPM if above — but herringbone is far less forgiving of unevenness. A 3mm hollow under a 2m plank is invisible; under herringbone it leaves a cluster of proud block edges that you feel underfoot and that wear through the finish. Budget for a smoothing compound on anything that is not a recently laid, power-floated screed. See subfloor preparation guide and floor levelling compounds for the full procedure.

Setting out herringbone

  1. Find the centreline of the room along the direction the pattern will "point". In a hall this is the centre of the hall; in a room it is usually towards the focal wall or window.
  2. Snap a chalk line. Dry-lay the first two rows (the "chase") along it with the point of each V sitting exactly on the line. Check square with a 3-4-5 triangle or a laser.
  3. Measure from the chase to each perimeter wall at both ends. If the room is more than ~10mm out of square over its length, decide now whether to split the error between both walls or hide it behind a border.
  4. Fix the first chase in adhesive and let it grab (typically 1–2 hours for MS-polymer) before working off it. Everything else keys off these two rows.
  5. Work outwards from the chase in both directions, then cut in the perimeter last.

A perimeter border (one or two straight blocks run around the room) hides the ragged 45° cuts, makes an out-of-square room look intentional, and is easier to fit than 45° scribes against a wavy wall. Price it separately — it is a genuine extra.

Setting out straight lay

Start from the longest, straightest wall, scribe the first row to the wall so the gap is constant, and leave the expansion gap behind it. Stagger end joints by at least 300mm (or 2–3× the board width on narrow boards) and avoid "stepping" patterns. If the room is out of square, the taper is absorbed in the last row, which is normally under a kitchen plinth, radiator or furniture. Run boards along the length of the room or towards the main light; across joists where secret-nailing to a timber subfloor.

Which pattern for which room

Pricing the job

Quote herringbone as its own line, not as straight lay plus a percentage. A workable structure:

Line Straight lay (20m² lounge, engineered oak) Herringbone (same room)
Material (incl. wastage) 21.4m² @ £40 = £856 22.5m² @ £85 = £1,913
Adhesive, DPM, trims £180 £220
Smoothing compound £0–£160 £160
Labour 20m² @ £28 = £560 20m² @ £48 = £960
Setting out / border Included £150–£300
Indicative total (ex VAT) £1,600–£1,760 £3,400–£3,550

The herringbone job here is roughly twice the price — which is normal, and customers accept it once the reasons are itemised. See wood flooring installation pricing guide for the full rate build-up by product type.

Frequently Asked Questions

Can herringbone be floated rather than glued?

Timber herringbone should be fully bonded. Individual blocks have no continuous tongue-and-groove run to lock a floating field together, so a floated solid or engineered herringbone creaks, gaps and lifts at the points. The exceptions are purpose-made click herringbone systems in laminate, SPC and some LVT, which are engineered to float; follow the manufacturer's instructions and allow their expansion gap. Over underfloor heating, bonding is also the better thermal choice for either pattern.

Why is my herringbone wastage so much higher than the supplier's 10%?

The published 10% assumes a square room with the pattern running square to the walls. Add bays, alcoves, a diagonal wall, or run the pattern at 45° to the room (a "diamond" lay), and the perimeter cuts increase sharply — 15–18% is realistic. Chevron (ends cut at 45° so the blocks meet in a continuous point) is worse still because every block is already cut and offcuts rarely re-use.

Does straight lay always run along the longest wall?

That is the default because it reduces the number of rows and makes the room look longer, but light direction matters more visually: boards running towards the main window hide the joints. On a timber subfloor where boards are secret-nailed, they must run across the joists regardless. If the longest wall and the light disagree, lay a few boards both ways and show the customer.

Can I lay herringbone on an existing floorboard subfloor?

Yes, but not directly. Overlay the boards with 6mm plywood (minimum) screwed at 150mm centres to give a flat, continuous bonding surface, check for movement and squeaks first, and confirm the moisture content of the boards is below 12%. The ply adds height — check door clearances and thresholds. This is standard practice for both patterns but essential for herringbone because board cupping shows through the small blocks.

Which pattern suits underfloor heating better?

Neither pattern is inherently better; the product thickness and certification are what matter. Keep timber to ≤15mm engineered with a 3–4mm wear layer, bonded with a flexible adhesive, and keep the floor surface temperature at or below 27°C. Herringbone's many small blocks actually cope slightly better with seasonal movement than wide planks, because each block moves a little rather than one wide board moving a lot. Commission the UFH to the manufacturer's heat-up schedule before and after laying.
