On our engineered hardwood, a box marked 70% full length is telling you how the boards inside were cut: most of them run the full 1900mm, and the rest are shorter random lengths. That ratio shapes how many end joints break the surface of a long plank engineered hardwood flooring job, which matters most in an open plan. Our engineered hardwood collection is graded three ways by length, and every figure below comes from the current boxes and prices.
Quick answer: what a 70% full length figure means
The figure describes boards. Our product pages list all three of our length grades as random length up to 1900mm, which is about 6.2 ft, and a full-length board is one that reaches that 1900mm maximum. On a 70% box, seven in ten boards are full length and the rest are shorter random lengths, so the grade tells you how much of the box runs long.
- Ultra-Premium Planks: 70% full length. 21 SKUs carry this grade and 19 of 21 are in stock.
- Premium Mixed Planks: 60% full length on our 6 1/2 in series. 10 SKUs carry this grade and 9 of 10 are stocked right now.
- Classic Mixed Planks: 40% full length on our 4mm series. 7 SKUs, and 7 of 7 are stocked right now.
- What it changes: a higher percentage puts more uninterrupted board length in the middle of the floor, and fewer short pieces to interrupt the line of the grain.
Our three length grades side by side
Every one of the 38 engineered hardwood SKUs in our catalogue carries one of these three length grades, listed next to width and wear layer. The table below uses a current box price and the coverage per box; the material figure is the box price divided by that coverage.
| Length grade | Full-length share | Plank width | Wear layer | SKUs in stock | Box price and coverage | Material per sq ft | Example colours |
|---|---|---|---|---|---|---|---|
| Ultra-Premium Planks | 70% full length | 7 1/2 in | 3mm | 19 of 21 | $97.00 per 19.42 sq ft box | $4.99 | Villa and Verita |
| Premium Mixed Planks | 60% full length | 6 1/2 in | 2mm | 9 of 10 | $95.71 per 20.24 sq ft box | $4.73 | Slate |
| Classic Mixed Planks | 40% full length | 7 1/2 in | 4mm | 7 of 7 | $97.00 per 19.42 sq ft box on six colours | $4.99 | Bourbon, Mocha, Pewter and other 4mm colours |
Prices checked October 6, 2026. Box prices and coverage come from our current catalogue.
The 40% grade holds the same $4.99 per sq ft as the 70% grade on its standard colours, so a lower length percentage does not by itself mean a lower price. Our 7 1/2 in series as a whole runs from $4.99 to $6.18 per sq ft across 28 SKUs, and 26 of those are in stock.
Ultra-Premium Planks: 70% full length at 1900mm
Villa and Verita are two of the 21 colours graded 70% full length. Both are 7 1/2 in wide with a 3mm wear layer, each box covers 19.42 sq ft, and the box price of $97.00 works out to $4.99 per sq ft. Our guide to 2mm, 3mm and 4mm wear layers explains what that top layer means for sanding and refinishing later.
A bedroom or a small den rarely shows off a length grade, because furniture and doorway cuts break up the run anyway. The 70% grade earns its keep where a single line of boards can be seen from one end of the room to the other.
Premium Mixed Planks: 60% full length on the 6 1/2 in series
Slate is one of the 10 colours graded 60% full length. It is 6 1/2 in wide with a 2mm wear layer, each box covers 20.24 sq ft, and $95.71 per box is $4.73 per sq ft. That is $0.26 per sq ft below the 70% grade, but the two series also differ in width and wear layer, so the gap is not a price for board length alone.
A 60% box still carries plenty of full-length boards. If the choice is coming down to how a plank width reads in a room, our wide plank versus narrow plank comparison works through that decision separately.
Classic Mixed Planks: 40% full length with a 4mm wear layer
The 40% group is our 4mm series: the same 7 1/2 in width and 19.42 sq ft coverage, with six of the seven colours at $4.99 per sq ft. The seventh, Driftwood, is $120.00 per box, or $6.18 per sq ft. Here the thicker wear layer is what sets the series apart, and a 40% box leaves more of the floor reading as shorter pieces.
What a higher full-length share looks like across a long run
End joints are the places where two boards meet end to end, and they are the one thing a length grade controls directly. A box graded 40% carries twice the share of short boards that a 70% box carries: six of every ten boards are shorter pieces against three of every ten. The same floor area therefore ends up with more of those joints when the lower grade is laid.
Sightlines are what make the difference visible. In an open plan where a kitchen, dining area and living room share one floor, the boards can run the length of the room before a doorway interrupts them, and every short board in that run adds another break. Our product pages describe the 70% boards as random length up to 1900mm with the majority at full length, and put the maximum plank at roughly 6.2 ft.
Spread a box out before the first board goes down, place the longest planks along the middle of the line of sight, and keep the shorter pieces for walls, closets and cut ends. That step helps a long run read as one continuous surface.
Material cost for 800 sq ft, by length grade
Flooring is sold by the box, so the length grade also moves the box count. Here is the material side of an 800 sq ft main floor with the 5% waste allowance our quotes use for material, which covers cuts and offcuts. Installation and delivery are not included here and are confirmed at quote.
| Line | 70% grade, 7 1/2 in | 60% grade, 6 1/2 in |
|---|---|---|
| Measured area | 800 sq ft | 800 sq ft |
| With 5% waste | 840 sq ft | 840 sq ft |
| Boxes needed | 44 boxes | 42 boxes |
| Material | 44 × $97.00 = $4,268.00 | 42 × $95.71 = $4,019.82 |
The 70% grade costs $248.18 more in material for the same floor and returns 7 1/2 in boards with a 3mm wear layer. Boxes are whole units, so both counts round up: 840 sq ft needs 44 boxes at 19.42 sq ft each, or 42 boxes at 20.24 sq ft each, and the waste allowance is what covers the offcuts from those boxes.
Which length grade suits your rooms
- A main floor seen in one view: the 70% grade. The wider plank and the higher full-length share keep the run as unbroken as the layout allows.
- Bedrooms and smaller rooms: the 60% grade, at $4.73 per sq ft, with a narrower plank for rooms where doorways and furniture interrupt the run anyway.
- A 4mm top layer on the spec sheet: the 40% grade, whose standard colours come in at the same $4.99 per sq ft, so the trade is board length for surface thickness.
- A condo with one long living area: our guide to engineered hardwood for Toronto condos sets out what to check with your building before you order.
How to check the full-length figure before you order
Where the number lives
On our product pages the length grade sits in the specification list, on the Length line beside plank width and wear layer. If a listing you are comparing does not show one, ask for it rather than guessing from photos.
What to ask for
Ask for the share of full-length boards and the maximum plank length in the same answer, because the percentage only means something next to the length it describes. A 70% figure on a short maximum length is a different floor from 70% at 1900mm. Our European oak buying guide covers the rest of the specification questions worth putting to a supplier.
What the grade does not tell you
The percentage says nothing about width, wear layer, grade, finish or colour, and it is not a quality rating. In our own range the 60% grade is also the narrower 6 1/2 in plank and the 40% grade carries the 4mm top layer, so read the rest of the specification next to it.
Long plank engineered hardwood: frequently asked questions
What exactly does the 70% figure on a box refer to?
It is the share of full-length boards in the box. Seven out of every ten boards on our 70% boxes are cut to the 1900mm maximum, and the remaining pieces come in assorted shorter lengths.
Is a 1900mm plank the same as a 6.2 ft plank?
To within rounding, yes. 1900mm converts to roughly 6.2 ft, and our Villa product page gives both figures for the same board.
Does a higher full-length share cost more?
No, not on its own. Our 70% and 40% groups both start at $4.99 per sq ft, and the engineered line reaches down to $4.73 per sq ft on the 60% group, which is narrower with a thinner wear layer.
How many boxes does 800 sq ft need?
With our 5% waste allowance you are buying for 840 sq ft. That comes to 44 boxes of the 70% grade or 42 boxes of the 60% grade, and boxes are only sold whole.
Do the 60% and 40% grades use shorter boards?
Not at the top end. Our product pages give random lengths up to 1900mm for the 60% and 40% grades as well; what changes is how many boards in each box reach that length.
