Introducing
Flooring Calculator
Getting your flooring quantity right the first time saves you money, delays, and that sinking feeling when you're two planks short on a Sunday afternoon. We've seen it happen more times than we can count — someone measures their lounge, orders the exact amount, and ends up scrambling because they forgot about wastage, doorways, or that weird alcove behind the TV unit.
This calculator takes the guesswork out. Punch in your room dimensions, select your flooring type, and we'll tell you exactly how many square metres to order — including the extra you'll actually need.
How to measure a room for flooring
You need a tape measure, a pen, and five minutes per room. Here's the process we walk every customer through:
- Measure the length and width of each room at the widest points. Measure in metres, wall to wall. For L-shaped rooms, split the space into rectangles and measure each one separately.
- Multiply length by width for each area, then add them together. A 5m × 4m lounge is 20m². A 3m × 2m hallway adds 6m². Include wardrobes and pantries if the flooring runs into them.
- Add wastage on top. Add 10% for standard plank installation. Go to 15% for herringbone, diagonal lays, or rooms with lots of angles and doorways — patterned floors create more offcuts.
The calculator above does steps two and three for you. Cuts at walls, around door frames, and at the ends of rows all consume planks, which is why ordering the exact room size never works out.
Why you order by the box, not the plank
Flooring is sold in boxes covering a set area — most of our hybrid flooring covers around 1.66m² to 2.2m² per box (the exact figure is on every product page). Your total is rounded up to whole boxes, so a 26m² job at 1.66m²/box means 16 boxes, not 15.7. A leftover box is worth keeping: planks from the same batch match in colour, so future repairs are invisible.
Pricing is simpler than it looks too — take the per-square-metre price on the product page, multiply by your total including wastage, and you have your materials cost. Our installation cost guide covers what installers charge on top.
Questions we get about flooring quantities
How much extra flooring should I order for wastage?
Order 10% extra for a standard straight plank lay, and 15% for herringbone, chevron, or diagonal patterns. Rooms with many doorways, angles or alcoves sit at the higher end. The extra covers cutting waste, the odd mis-cut, and a few spare planks for future repairs.
How many square metres are in a box of hybrid flooring?
It varies by range — our 6.5mm and 9.5mm hybrid boxes cover roughly 1.66m² to 2.2m² each. The exact coverage is listed in the specifications table on every product page, and the calculator on each product page converts your square metres into boxes automatically.
Should I include wardrobes and cupboards in my measurements?
Yes, if the flooring runs into them — built-in wardrobes are usually floored to the back wall. Walk-in pantries and linen cupboards are the same. Leave them out only if you're keeping the existing floor inside.
What happens if I order too little?
You can order more, but there are two catches: dye batches vary slightly between production runs, and stock moves. A top-up ordered months later may not match perfectly. That's the real reason for the 10% buffer — it's much cheaper than a visible colour step in the middle of your living room.
Do stairs change the calculation?
Yes — stairs are measured per tread and riser rather than by area, and they need stair nosings and glue rather than click-lock alone. Call us on 0431 311 633 with your stair count and we'll work out the quantities with you.
Does the calculator work for any flooring type?
The maths is the same for hybrid, laminate, vinyl and engineered timber — area plus wastage, rounded up to whole boxes. Only the per-box coverage changes between products.
Can I get help checking my numbers?
Send us your room measurements via the contact page or call 0431 311 633 and we'll check your quantities before you order. If you're in South East Queensland, our Brisbane guide covers click-and-collect from our warehouse, and we deliver Australia-wide. Not sure which floor yet?
