Important Information
This guide has been produced to enable you to measure a room for your chosen floorcovering and should not be considered an installation guide.

For your calculation you will need paper, a pen or pencil, tape measure, calculator and information on the width/sizes available in your chosen products.

When measuring your rooms you should always ensure that you keep the flooring running in the same direction to maintain texture, pattern and colour consistency. If you change the direction then the pattern, texture and the pile of the carpet will reflect light differently.

Quick Room Calculator

10cms needs to be added to the length when doing your calculations to allow for cutting in during installation. Note: The calculator will automatically allow for this.

For more informaton check the guides below on how to measure your room page

Note: Minimum order of 1.5m length carpet

    Room Width:    Metres
    Room Length:    Metres

You must order a minimum length of 1.5m for your carpet

You will need to measure your room at the widest point taking into account any bay windows and door entrances as below. Once you have these measurements you need to add 10cm the length to allow for cutting in during your installation. The calculator will automatically allow for this.

When you have the room width you need to check that it is less than the width of the carpet you are buying to avoid any joins, for instance if your room width is 4.4m wide and the carpet you are buying is available in 4m and 5m widths then you can buy the 5m wide product. If the carpet is only 4m wide then you will need to buy either the length of the room by the width twice and use the second piece as a filler to give you your 4.4m width or if you are fitting another room you may find that you have excess from this room that can be utilised as the filler.

When measuring a hallway, stairs and a landing you will need to take additional measurements. You should start by measuring the length and width of the hallway as you can see from the plan to the right. You should stand with your back against the wall and the length of your hallway will become your length and the measurement across your hall would become your width.

You need to measure the stairs taking into account the tread and the riser. For ease and if these are all the same you can measure the bottom riser and tread and then multiply this by the quantity of steps.

When this has been completed you then need to measure your landing.

Once all measurements have been taken you can plan what you need to buy taking into account the width of carpet you wish to purchase. In the event that the width of the hallway or landing is greater than the width of the available flooring then you will need to include a join. This area can be used as an infill from excess from the other areas if available.

  1. Seams should run towards primary light sources where possible and be kept to a minimum where possible.

  2. Seams should always be kept to a minimum and avoided where possible.

  3. Carpet should all run in the same direction.

  4. Always begin measurements in the centre of doorways rather than the bottom of walls.

  5. You should allow extra in your purchase for patterned goods such as Wilton, Graphics etc to allow for pattern matching.

  6. Colour is difficult to match between dye batches and different widths so we would recommend that you purchase all you require at the same time specifying all cuts to come from the same dye batch.
