Karndean Design Strip DS16-3-2 Charcoal 3mm(w) x 2mm(t)

To complete the look of your Karndean floor, add a Karndean Charcoal DS16 Design Strip. Place these between tiles to create a natural grouting effect or to enhance the design of your floor.

To calculate how many boxes of design strips you need for your floor, use this guide.

It's impossible to know the cost of a new floor without knowing how much of it you need. Unless you're a maths whizz, it can be pretty daunting to start measuring your room for laminate flooring, wood flooring or LVT flooring, so we have a simple method you can use.

How to measure your room example - simple room

If your room is a rectangle, this is as simple as measuring the length and width of your room and multiplying them together. Therefore if your room is 6 metres long and 3 metres wide, the area will be 18 metres square because 6 x 3 = 18

How to measure your room example - L-shaped room

If your room isn't rectangular, we recommend splitting it into rectangular sections. Multiply the width and length of each rectangle together to find the area. Then, add the areas of each rectangle together to find the total area. If you have an L shaped room, for example, this can be split into 2 rectangles.

How to measure your room example - complicated room layout

And if you've got a complicated room, this method still works. Simply split the room into as many rectangles as needed. Multiply the length and width of each rectangle to find the areas, then add them all together to find the total area. (Remember to jot down the measurements as you go along!)

Tip message to jot down measurements as you go along

Important tip

Important tip: it's standard to add an extra 5% on to your area to allow for the usual wastage that occurs during installation. To calculate this, you'll need to multiply the total area by 1.05. However, parquet and tiled floors where the installation starts in the middle of the room require 7-10% wastage as it's likely you'll have to cut more boards than with a regular, strait-lay design.

Measuring for Carpet

First, you'll need to measure the length & width of your room. You'll also need to allow for extra material for the installer to "cut in". When carpets are fitted, they need to run at least 5cm up each wall so they can be trimmed more accurately to fit against your skirting boards.

The most common widths for carpets are 4 & 5 metres. The width always refers to the width of the carpet, and the length is the other measurement, be it longer or shorter than the width. For example, if your room is 2.7 x 3.9 metres, you would opt for a 4-metre width carpet and purchase 2.75 metres in length, giving you 11m2 in total. If you want the design of your carpet to be in a lengthways direction, you'd need to purchase 4 metres of the 4-metre-wide carpet, giving you 16m2 in total.

Measuring Carpet for Stairs, Hallways & Landings

Draw a detailed plan of all of the flat areas involved, including any rooms that you intend to do in the same quality and colour as your hall, stairs and landing (HSL). Write each measurement against each wall.

Make a note of how many straight stairs you have and measure the width of these stairs. We recommend allowing 50cm extra in length for each straight step.

Make a note of any ½ landings, winders & kites that you may have (kites and winders are triangular-shaped stairs that create a curve in your staircase). Measure the length and width of each of these steps remembering that the length is the measurement that runs over the nose of the step and the width is the measurement running from side to side as you look up the staircase.

You'll need to decide whether to use 4.00 or 5.00-metre width carpet. Make sure you check which widths are available in your chosen carpet before you make this decision as you don't want to work it out in 5.00-metre width to realise your carpet only comes in 4.00-metre width!

Now the fun part! Draw a rectangle on your piece of paper and write the width at the top of the page and then try and fit all of the pieces that you need into that rectangle, ensuring that all of your relevant measurements will work within the space you have allowed. Diagram 1 shows an example of a HSL plan.

Remember, if you are carpeting some rooms in the same carpet that you intend to put on your stairs then you can use waste material from the rooms to use on the stairs, this may mean buying less carpet for your HSL.

Delivery Terms and Conditions

Standard deliveries are kerbside (you'll need to carry goods into your property) and can be made on anything from a van to an 18 tonne lorry, so it is assumed that the delivery address will be easily accessible for any large vehicle. Please be aware most of our shipments will be on a pallet and this will be left with you at the point of delivery. If access is likely to be a problem please inform us at the time of order to discuss alternative delivery options.

We strongly advise against booking installers until goods have been received and checked as, regrettably, we cannot be held responsible for any consequential losses.

Your new flooring should also be given time to acclimatise.

Failed Deliveries

If your order arrives as arranged but we're unable to deliver because there's nobody home, the goods are refused, there's inadequate help available, or the order is requested to be changed/cancelled within 48 hours of your delivery (excluding weekends), you will be liable for any additional costs incurred for the goods being returned, or the goods being redelivered.

If after a failed delivery you do not re-arrange delivery, we will contact you for further instructions and may charge you for storage costs and any further delivery costs. If, despite our reasonable efforts, we are unable to contact you or re-arrange delivery we may end the contract.

Order not as expected

It is important to check the packages for any visual damage to the goods. In the rare event that you receive damaged goods or there are missing items, please make sure it is noted on the courier's paperwork. If you are not able to inspect the goods at the point of delivery, we strongly suggest that you contact us directly as soon as possible to make sure we are aware of the problem so that we can resolve it swiftly.
