Planning a new lawn? Naturally you’ll need to know the cost before you embark on the project. Here’s our turf cost calculator.

How to calculate the cost of a new lawn from turf

First: calculate how much turf you’ll need

Measuring

Before you can use the turf cost calculator, you need accurate measurements of the area to be turfed.

Many moons ago, I took a phone call from a gentleman needing a quote for turf. He also wanted help to work out how much turf to buy. I asked him for the relevant measurements. He told me that his garden was 28 steps wide and 92 steps long and that he wanted to turf about one third of it.

Can you spot his mistake?

First of all, he was measuring in steps. Not helpful – at least without knowing his inside leg measurement and how flexible he is. Second he was guessing that he wanted turf for 1/3 of the area – but he wasn’t sure.

Mark out the area to be turfed and measure it accurately. Remember to check all measurements as once your turf has been ordered and delivered it could be expensive to put mistakes right

When you calculate your turf requirements, it’s best to follow these 3 steps.

  1. Mark out the area. Look at it from above, from the North, South, East and West and tweak the size and shape until you’re happy with it.
  2. Measure each of the sides. Use a laser measure or a tape and check everything carefully. If your lawn is to be a circle, measure the widest point. If it’s a triangle, measure the longest side and then measure from the point to the longest side. Do it twice so that you can check the measurements are accurate.
  3. Make all your measurements in the same units. Ie all centimeters, all metres or all inches.  Don’t try to mix and match – it doesn’t work. (trust me, I’m a dressmaker as well as a gardener)

Next: Calculating

Not everyone is a whizz at maths, I’m certainly not. So here’s what you need to do with your measurements.

You could, use squared paper to draw an accurate plan of your new lawn. The side of 1 square = 1 metre.  Then all you need to do is count the squares inside the outline and that should tell you how many rolls of turf you’ll need.

Remember, if you’re buying from Turfonline, 1 roll of turf covers 1 square metre.  Other retailers may offer different sized turfs – so check first before you place your order.

Alternatively, calculate the area using a simple sum and then order over the phone. The sales person ought to be able to help you double-check your maths.

For a square or rectangular lawn, multiply the length of the lawn by its width.

For example, if your new lawn is to be 14 metres long by 4 metres wide, you will need enough turf to cover 14 x4 = 56 square metres.

In Turfonline terms that’s 56 rolls.  If I were you, I’d order 60 rolls, just in case there’s some wastage when you trim the pieces to size.

Pricing your turf

To get a quote for your turf, you could phone or email your supplier, or, if they have an online shop, you can plug your details into the website without committing to buy.

Most retailers offer more than one type of turf. You can choose which one is most suitable for your project and ask for a quote for that. Or you can compare the prices of each grade and use that information to help you decide.

Be very mindful that not every turf seller shows the whole price on their website. Some do and some don’t. You may or may not have to add on a delivery cost. You may also be asked to pay VAT.

When you are comparing prices, make sure you compare like for like and ensure all VAT and delivery charges are included in the final price.

Using Turfonline’s Turf Cost Calculator

The Turfonline website has a handy turf cost calculator built in. We call it our project quote.

If your lawn is square, rectangular or circular you can simply type in the measurements and the turf cost calculator will work out how many rolls of turf you need.

You then have the option of adding an extra 5% to allow for wastage. Believe me, it’s worth doing. It’ll cost a fortune if you can’t finish the job and need to have just a few rolls delivered to complete the project.

Once you have agreed the quantity you need, press the button that says “see turf options”.

From here, you can compare the cost of each grade of turf. This part of the project quote includes VAT but there may be a moderate delivery charge to add on, depending on where you live.

Select your turf by clicking on the button and then you’ll be asked to add in your postcode and preferred delivery date. Once that’s done, you’ll be shown delivery options.

Make your selection and your quote will be visible on the screen. You’ll also see a reminder to order topsoil if you need it as well as important accessories.  I can personally recommend the laying boards (I use mine for all sorts of jobs in the garden) and the preturfing fertiliser to get your lawn off to a good start. But that’s your choice.

If you’re ready to order, you can proceed to the checkout. If not, print out your quote and keep it until you need it.
