Choosing the Right Waste Allowance
Most flooring projects require a small amount of extra material to allow for cuts and mistakes.
- 5% – Straightforward square rooms
- 10% – Recommended for most rooms
- 15% – Rooms with lots of corners
- 20% – Herringbone or complex layouts
Ordering enough flooring at the beginning helps avoid colour differences between production batches if you need extra packs later.

Not sure which flooring to choose?
Laminate Flooring
Affordable, durable and easy to install. A popular choice for living rooms, bedrooms and hallways.

Engineered Wood
Engineered wood flooring combines the beauty of real hardwood with improved stability, making it suitable for many modern homes. It’s a premium option that offers a natural wood finish with greater resistance to changes.
Solid Hardwood
Made from natural timber throughout, solid hardwood flooring offers timeless beauty and exceptional longevity. It can often be sanded and refinished multiple times, making it a long-term investment for your home.
Carpet Flooring
Soft, warm and comfortable underfoot, carpet is a popular choice for bedrooms, living rooms and family spaces. It’s available in a wide range of colours, textures and pile types to suit different homes and lifestyles.
Floor Tiles
Durable, water-resistant and easy to maintain, floor tiles are an excellent choice for kitchens, bathrooms, hallways and utility rooms. Available in ceramic, porcelain and natural stone finishes to suit every style.
🛒 What else will you need?
Here are some of the most common tools and accessories you’ll need to install laminate, engineered wood or LVT flooring. Browse the recommendations below to help complete your project.
1. Underlay
Helps reduce noise, smooth out minor imperfections and improve comfort underfoot.
2. Flooring installation kit (Most important)
This is one of the easiest affiliate recommendations because it’s a standard kit that usually includes a tapping block, pull bar, mallet and spacers.
3. Tape measure
Accurate measurements are essential before ordering flooring and planning cuts.
4. Knee Pads
Installing flooring often means spending long periods kneeling, so a comfortable pair of knee pads can make the job much easier.
9. Flooring Underlay Tape
If using underlay rolls, sealing the joins helps create a neater installation and can improve moisture protection depending on the underlay type.
Before You Start
A simple checklist:
- Measure every room twice
- Check your subfloor is level
- Allow flooring to acclimatise
- Order 5–10% extra flooring
- Buy all packs from the same batch if possible
Frequently Asked Questions
How much extra flooring should I buy?
For most projects, allowing 10% extra flooring is recommended to cover cuts, mistakes and future repairs. More complex layouts such as herringbone may require 15–20% extra.
Can I use this calculator for laminate flooring?
Yes. The calculator works for laminate flooring, luxury vinyl (LVT), engineered wood, solid hardwood and other flooring sold by square metre. Always check the manufacturer’s pack coverage before purchasing.
Can I calculate multiple rooms?
Currently, the calculator is designed for one room at a time. If you’re flooring multiple rooms, calculate each room separately and add the totals together.
(You can later upgrade the calculator to support multiple rooms.)
How do I calculate flooring packs?
Simply enter the pack coverage shown on the flooring packaging. The calculator will estimate how many packs you’ll need based on your room size and selected waste allowance.
Does this calculator include waste?
Yes. You can choose a waste allowance of 5%, 10%, 15% or 20%, depending on the complexity of your flooring layout.
