How To Estimate Pavers When Using A Pattern

How to estimate a paver patio

Pavers are often installed in a pattern using different sized tiles. The trick to figuring paver quantities necessary for these patterns is to assemble the repeating pattern, estimate the square footage of the pattern itself, and then calculate how many repeating patterns are needed.

For instance, if your pattern requires two 4 x 8 pavers for every one 8 x 8 unit, you can calculate the square footage of all three pavers together and then find how many sets of pavers are needed: patio sq ft ÷ 0.89 sq ft.

In addition to repeating patterns using different sized pavers, different layout patterns can influence how much material you should order.

For instance, a herringbone pattern requires more cuts than a linear grid, resulting in more waste material. We recommend ordering 20% more material when using patterns laid out at an angle as they result in more cuts and waste material.See paver layout patterns

So How To Calculate How Many Pavers I Need

The first thing that you need to do in order to discover how many pavers you need for your project us to measure its area. So, lets say that you want to build a patio. You will need to ensure that you measure both the length as well as the width. Since you need to determine the square footage of the patio, all you need to do is to multiply the width by the length of the patio.

Make sure to check out our Paver calculator.

Then, you need to discover how many pavers you need for your patio. The truth is that pavers dont all have the same size or shape. Below, you will be able to see a table with the most common sizes of pavers. Nevertheless, and to make things as simple as possible, lets just assume for now that the paver size that you want to use id 12 X 12. So, in this case:

144 / 12 X 12 = 144 / 144 = 1

This means that you need one paver per square foot.

As you can see, you already determined the square footage of both the patio as well as of the paver that you want to use. So, in order to discover how many pavers you need, you just need to divide the square footage of the patio by the square footage of the paver.

Three: Calculate Pavers Needed

After you have found the square footage of both the project and the paver, determining the number of pavers needed is as simple as dividing the patios square footage by the pavers square footage.

Formula to Estimate Pavers:

pavers needed = patio sq ftpaver sq ft

Most experts suggest ordering 5%-10% more pavers to account for broken pavers or cuts.

But What If My Measurements Are In Different Units

In the examples above all the measurements were in square footage.

However, in our calculator there are multiple options for the units of each measurement that are available for you to use.

You can calculate in inches, feet, yards, centimeters and meters.

Simply select the correct unit in the drop-down options and our calculator will work out the following conversion:

$$1\,foot = 12\,inches = 0.33\,yards = 30.48\,centimeters = 0.3048\,meters$$

How To Calculate The Amount Of Pavers You Need For Your Patio Project

Paver Calculator and Price Estimator

Calculating what materials you need for your patio is actually quite easy, and Unilock has many resources like our Paver Calculator and Wall Calculator to help with this process. The part that takes more consideration is planning for what you really need in your outdoor space. At the end of the day, it boils down to how many people you typically entertain on your patio and how often.

There is no fixed rule about the amount of square footage that you require for a certain number of people. There are however, two very important factors when deciding on the size of your patio:

  • The number of people that will be using the patio on a regular basis.
  • What amenities you wish to have as part of your patio area such as a fire pit or grill island.
  • If you want to incorporate patio furniture you already own, it is important to consider this in your plans so that your new patio can accommodate it. This is a common mistake homeowners make, and after the install realize that their furniture is far too bulky, or looks lost in the new space. If possible, avoid purchasing furniture until your outdoor living room is complete.

    As you can see in the plan below, a smaller area will be just fine for a patio area for a dining set and a barbecue. Even though this patio area is only about 320 square feet, it still works comfortably for dining or lounging.

    How To Calculate How Many Pavers You Need

    Justin DoradoAugust 13, 2018

    When you want to build your own driveway, pool deck, walkway or patio, pavers are one of the best materials that you can use. The truth is that they are extremely durable and they come in a wide variety of textures, shapes, and even colors.

    Discover the calculators website hub.

    However, one of the questions that many people have in order to start building their own driveway, pool deck, walkway or patio is how to calculate how many pavers I need. The reality is that you dont want to order too much or youll be throwing money away, but you dont want to run out of pavers in the middle of the project.

    Determining The Size Of The Paver Project

    The first step is to decide what shape, size, and design you want your patio or walkway to be. Lets say you want to design your own patio and you want it to be large enough to accommodate outdoor furniture and a dining set so that you and your family can enjoy meals outside. Consider that youll want to have enough room to slide out the chairs and walk around them. If you want planters or a fire pit, take that into account as well.

    If youre hoping to create a walkway, the standard width is 36 inches, but 48 inches allows two people to walk comfortably side-by-side. Consider that a wheelchair needs a walkway to be at least 36 inches but should also have a 60-inch-wide turnaround area.

    Now that you have an idea how large of an area you are trying to cover, you can get onto estimating the amount of materials youll need. Weve laid out several equations below for you to use as guides and adjust to fit your project but know that your material needs may vary depending on the specifics of your projects design.

    What Is Crushed Stone

    Crushed Stone is a man-made construction aggregate typically produced in a quarry by passing stones through a crushing machine. . The crushed stone is typically used as a base or underlayment, for example, where the concrete of a patio will rest. It’s also used for drainage and landscaping. It is offered in a variety of sizes and stones. Crushed stone can be purchased at home improvement stores, garden centers, or directly from a quarry.

    How to Build a Round Paver Patio

    Homeowners use paver stones to cover an outside area with a tough but natural-looking surface. The stones cover pathways, drives and patio areas. And their small size makes them ideal for creating narrow borders and curved edges. Determining how many pavers are required for a project need not be a job you pay a builder or landscape gardener to do it’s quite straightforward if you know the size of the pavers and the size of the area to be covered.


    Measure the length and width of a sample paver. Alternatively, obtain the measurements from a brochure or staff member at your supplier.


    Multiply the width of the paver by its length to determine the top surface area. For example, a paver 1 foot long, with a width of 6 inches, has a top surface area of 0.5 square feet because 0.5 x 1 = 0.5.


    Draw a rough sketch of the total area to be covered in pavers, and subdivide the area into simple regular shapes such as rectangles, circles and triangles. For example, an “L” can be reduced to two rectangles — one up and one across — and a hexagon is just six triangles with their tips touching in the center and their bases forming the sides of the hexagon.


    Measure the length and width — or radius for curved shapes — of each subsection, and record the measurements on the sketch plan.


    Determine the area of each shape by substituting the measurements into the appropriate formulas. For example:

    What Kind Of Sand Do You Use Between Pavers

    Most people know that before laying stone pavers, you must start with a top layer of paver sand. This type of sand should be granular and coarse. When the sand gets compacted, the edges grind together. This process locks the layer of sand in place to prevent movement or erosion.

    Although concrete sand works quite well, some people may also use mason sand. However, neither of these types are the best options. Loose-fill sand tends to wash away after time goes by or when it starts raining heavily. This is why manufacturers have developed special paver sand to make sure that everything stays in place.

    There are some types of paver sand which soften after getting wet. Although this type of sand allows for more flexibility, it may also cause erosion issues. Therefore, you may have to reapply the sand frequently to make sure that your pavement doesnt fall apart.

    Finally, you may also use polymeric sand. This is a type of granular sand material placed within the joints and cracks between stone pavers. The sand serves as a way to interlock the units while maintaining the integrity and beauty of the pavers. As you can see, when it comes to paver sand, you have quite a few options.

    Crushed Stone Vs Gravel

    The angular surface, roughness, and larger size of crushed stone make it a popular choice for gardens and pathways. It provides solid traction, doesn’t easily sink into the ground, and resists weed growth. By comparison, granite has a rounder, more natural appearance that’s a cost-effective option commonly used on driveways. For your next project, it really comes down to a matter of preference and use.

The laying pattern for this product uses a suggested area with the dimensions of 3.6m x 2.7m .

    Therefore, we always recommend that you measure your area in metres rather than feet. Dont worry though, if you are more comfortable working in imperial measurements, then give us a call on 0800 032 6306 and we can convert it for you.

    Find Out The Total Project Area

    Paver Calculator and Price Estimator

    What shape is your project area like? Rectangular? Square? Irregular? Were only asking because the easiest way to find the total area of your project is to estimate it as simple geometric form.

    If you have a rectangular project area, to calculate it you just need to measure width, length and then multiply. For a circular shape, you will need to find the radius, raise it to the power of 2 and multiply by Pi .

    If your project is irregular, the best thing you can do is to divide it into rectangles of different sizes and sum up their areas.

    Dont be a perfectionist, thats why we will be adding a safety factor at the end. Remember you just need to estimate the area.

    How Many Pavers Do I Need Per Square Foot

    pavers per square footpaversquaresquaresquare footsquarepaver

    The next step is to find the square footage of paver you want to use. Assuming the paver size is 12 x 12, multiply 12×12 and then divide 144 by the answer, ie. 144/ = 1.0. That means you need one paver per square foot, which makes sense since a 12 x 12paver is 1 square foot.

    Subsequently, question is, how many bricks do I need for a 12×12 patio? Divide 144, the number of square inches in one square foot, by the square inches of the brick to determine the number of bricks needed to cover 1 square foot of patio surface. For the standard brick size of 32 square inches, 4.5 bricks are needed to cover 1 square foot of patio.

    Hereof, how many pavers do I need for a 10×10 patio?

    Multiply the number of pavers needed to cover one square foot of patio by the number of square feet of the patio. In this example, 5.14 pavers are required per square foot for a patio that is 375 square feet. 5.14 times 375 equals just over 1,927 brick pavers required to complete the patio.

    How To Calculate The Number Of Pavers Needed For A Walkway

    You can beautify your walkway with old-style pavers. Pavers are small bricks, tiles or stones that are placed throughout the area of the driveway or walkway. This serves the purpose of paving, but offers an aesthetically unique appearance. Estimating the number of pavers required for an area can be challenging, but it need not be. All that is required is to measure the intended area and figure out how many pavers can fit in that area.

  • Measure the length and width of the walkway, in inches.

  • Multiply the length and width together to calculate the total area. As an example, if you measured 144 inches by 240 inches, then you would multiply those two numbers to achieve 34,560 square inches.

    If you had previously measured in feet, you can convert the area to square inches by multiplying by 144.

  • Add the walkway length and the width together and multiply by two to calculate the perimeter. As an example, in the example, 144 inches plus 240 inches, gives you 384 inches. Multiplying this number by 2 gives you a walkway perimeter of 768 inches.

  • Measure the length and width of one paver. Multiply those figures to calculate the area of a paver. As an example, a paver which measures 4 inches by 8 inches would have an area of 32 square inches.

  • Divide the walkway area by the paver area to calculate the number of pavers that will fit. In the example, you would divide 34,560 by 32, which tells you 1,080 pavers will fit.

    Formula For Needed Crushed Stone

    Use this formula to determine how much crushed stone you will need for your project:

    / 27 = cubic yards of crushed stone needed

    In the construction world, most materials are measured in cubic yards. Multiply the length , in feet, by the width , in feet, by the height , in feet, and divide by 27. This will tell you how many cubic yards of crushed stone you need.

    As an example, let’s say your DIY project is a patio, and it calls for the use of crushed stone as a base. If your patio is 20 feet long and 10 feet wide, and you need 6 inches of crushed stone for the base, you would plug those numbers into formula, as follows:

    / 27 = 3.7 cubic yards

    When using this equation, make sure all of your measurements are in feet. Since we needed 6 inches of crushed stone, we used 0.5 feet for the height .

    If your number comes out as a fraction , round up. In the example above, you would round the 3.7 cubic yards of crushed stone to 4 cubic yards of crushed stone. It is better to have a little extra than to run short.
