Flooring Calculator m2: Packs of Hybrid and Laminate

Estimate only. Check product labels and the building rules in your state or territory before you buy or build.

Quick answer

Multiply each room’s length by its width, add the rooms together, add 10% for offcuts (15% for a diagonal layout), then divide by the square metres in one pack and round up. A 4 × 3.5 m room is 14 m², or 15.4 m² with 10% waste, which is 9 packs of 1.873 m² hybrid planks.

How to use the flooring calculator

Measure each room wall to wall at floor level and enter its length and width in metres. Add a room for every space that gets the same flooring, or switch to Total area if you already know the square metres.
Choose the flooring type and the layout. The layout sets the waste allowance: 10% for straight rows, 15% for diagonal and herringbone. You can change the percentage under Waste, doorway width and product sizes.
Type the m² per pack printed on your pack. The number of packs updates as you type and is always rounded up to whole packs.
Under Skirting, scotia and underlay, enter the number of doorways to get the length of skirting or scotia and the number of lengths to buy. Underlay starts switched off for hybrid planks, which have it attached, and on for laminate and engineered timber.

How do you work out how much flooring you need?

Add up the floor area, add a waste allowance, divide by the area one pack covers and round up. Flooring is sold in whole packs, and each pack states how many square metres it covers. The allowance pays for the offcuts at the ends of rows and along the walls that are too short to use again.

Skirting and scotia follow the walls instead of the floor: add up the room perimeters, take off the width of each doorway, and divide by the length of one piece. Underlay covers the floor area itself, so it gets no waste allowance and is rounded up to whole rolls.

floor area = length × width, added up over the roomsarea with waste = floor area × (1 + waste % ÷ 100)packs = area with waste ÷ m² per pack, rounded upskirting or scotia length = room perimeters − doorways × doorway widthlengths to buy = skirting or scotia length ÷ piece length, rounded upunderlay rolls = floor area ÷ m² per roll, rounded up

How many packs of flooring do I need for my room?

A 4 × 3 m room needs 8 packs of 1.873 m² hybrid planks with a 10% waste allowance, or 6 packs of 2.508 m² engineered timber. The table works out other room sizes the same way: length × width, plus 10%, divided by the pack size and rounded up. Both pack sizes come from one maker’s Australian product pages.

Packs of flooring by room size, straight layout with a 10% waste allowance (pack sizes in m²)
Room (m)	Area with waste (m²)	Packs of 1.873	Packs of 2.508
3 × 2.5	8.25	5	4
3 × 3	9.9	6	4
3.5 × 3	11.55	7	5
4 × 3	13.2	8	6
4 × 3.5	15.4	9	7
4.5 × 4	19.8	11	8
5 × 4	22	12	9
6 × 4	26.4	15	11
6 × 5	33	18	14

For a diagonal or herringbone layout, set the waste allowance to 15% in the calculator instead.

Worked examples

Hybrid planks in a 4 × 3.5 m bedroom

The bedroom is 4 m by 3.5 m, so the floor is 4 × 3.5 = 14 m². Laid in straight rows, it gets a 10% waste allowance: 14 × 1.1 = 15.4 m². The hybrid planks come in packs of 1.873 m², and 15.4 ÷ 1.873 = 8.22, so buy 9 packs. Together they cover 16.86 m².

The perimeter is 2 × (4 + 3.5) = 15 m. Taking off one 0.9 m doorway leaves 14.1 m of skirting or scotia, which is 6 lengths of 2.4 m. These planks have underlay attached, so the calculator starts with underlay switched off.

Engineered timber in a 6 × 4.5 m living room

The living room is 6 × 4.5 = 27 m². Laid in straight rows with a 10% allowance, that is 27 × 1.1 = 29.7 m². The engineered timber comes in packs of 2.508 m², and 29.7 ÷ 2.508 = 11.84, so buy 12 packs, which cover 30.1 m².

The perimeter is 2 × (6 + 4.5) = 21 m. Two 0.9 m doorways leave 19.2 m, exactly 8 lengths of 2.4 m. The product page lists a 20 m² underlay as an accessory for these boards, and 27 m² of floor takes 2 of them.

How much extra flooring should I buy?

Buy 10% more than the floor area for straight rows and 15% more for a diagonal layout. Quick-Step tells buyers on its UK product pages to order 10% extra to cover cutting loss, and Egger’s guide gives the same 10% for waste and mistakes, rising to 15% for less experienced installers and for patterned or tile-look boards. A hardwood maker gives 10% to 15% for a diagonal layout, because every board along the walls is cut at an angle. An Australian timber flooring supplier gives 10% for plank flooring in areas under 100 m², and 7% above that.

The same supplier gives 15% for herringbone and chevron floors under 100 m² and 12% above that, so the calculator starts herringbone at 15%, the same as diagonal. If your product’s installation guide gives a number, type that into Waste allowance instead. Raise the percentage for rooms with many corners, built-in robes or a fireplace hearth to cut around.

How many square metres are in a pack of flooring?

The packs we checked cover 1.835 to 2.508 m², and the figure changes with board size. These are the products the calculator starts with, taken from the maker’s Australian product pages.

Coverage per pack, roll or length of flooring products sold in Australia
Product	Size checked	Coverage
Hybrid vinyl plank	1494 × 209 × 6 mm, 6 planks, underlay attached	1.873 m² per pack
Laminate	1380 × 190 × 8 mm, 7 planks	1.835 m² per pack
Engineered timber	2200 × 190 × 13 mm, 6 boards	2.508 m² per pack
Solid timber	No pack size confirmed	Starts at 2 m²: type your own
Underlay	Listed for laminate and engineered timber	20 m² or 50 m²
Scotia	17 × 17 mm	2400 mm per length

Always use the coverage printed on your own pack or roll.

Common questions

How many packs of flooring do I need for a 4 × 3 m room?

A 4 × 3 m room needs 8 packs of 1.873 m² hybrid planks. The floor is 12 m², and with a 10% waste allowance you need 13.2 m². Dividing 13.2 by 1.873 gives 7.05, which rounds up to 8 packs covering 14.98 m². With larger 2.508 m² packs of engineered timber, 6 packs are enough.

Do I need underlay under hybrid flooring?

No, not if the planks have underlay attached, as the hybrid planks the calculator starts with do, so it starts with underlay switched off for them. It switches underlay on when you choose laminate or engineered timber. Use the underlay the installation guide names: the same maker lists a 20 m² underlay as an accessory for its engineered boards, also sold in 50 m², so a 14 m² floor takes 1 roll.

Which flooring type do I choose for hybrid flooring?

Choose Hybrid or vinyl plank, then check the m² per pack against your own pack. Quick-Step Australia sells its Bloom planks in a range called Hybrid Vinyl, built from several layers with waterproof components and joined with a click system, and the Bloom pack we checked covers 1.873 m². The type you pick only sets the starting pack size, so the count is right whenever the coverage matches your pack.

How much skirting or scotia do I need for a room?

You need the room perimeter minus the doorways. A 4 × 3.5 m room has a perimeter of 15 m, and one 0.9 m doorway leaves 14.1 m, which is 6 lengths of 2.4 m. Scotia can also run along skirting you already have, so the same length applies. Each corner is mitred, so buy one more length if the room has several corners.

Should I buy a spare pack of flooring?

Yes, one or two spare packs are worth keeping. Egger suggests an extra pack or two, especially when the flooring comes from a limited batch, and a hardwood maker recommends one or two extra cartons so that boards damaged later, for example by a water leak, can be replaced with matching ones. The calculator does not add these spares, so add them to the pack count yourself.

How do I measure an L-shaped or open-plan area for flooring?

Split the floor into rectangles, measure each one and enter them as separate rooms. A 6 × 4 m living area with a 3 × 2 m dining nook is 24 + 6 = 30 m², which is 18 packs of 1.873 m² with a 10% allowance. Do not use the two perimeters for skirting, because the line between the rectangles is not a wall: measure the real walls and type their total into Wall length for skirting or scotia.
