Start with a Site Plan and Measurements

Before you buy a single paver, measure your patio space and draw it to scale on paper. Use a tape measure to find the length and width of the area, then sketch it on graph paper where each square represents one foot. Mark any fixed obstacles: the house wall, trees, steps, or existing structures. This drawing becomes your reference for every decision that follows.

Measure twice and write the numbers down. A patio that is 12 feet by 16 feet is not the same as one that is 12 feet by 15 feet when you are ordering materials. Take photos of the space from different angles so you can review them later when you are choosing paver sizes and patterns.

Key Takeaways

  • Draw your patio to scale on graph paper and mark all fixed obstacles before choosing paver size or pattern.
  • Select paver dimensions that divide evenly into your patio length and width to minimize cutting and waste.
  • Lay out pavers in a dry run on the ground to test your pattern and spacing before you prepare the base.
  • Plan for a slope of 1/8 inch per foot away from the house so water drains and does not pool.
  • Mark the layout with chalk lines or spray paint so you can follow it when you begin setting pavers in sand.

Choose Paver Dimensions That Fit Your Space

The size of your pavers determines how many cuts you will need to make and how much waste you will have. A patio that is 12 feet by 16 feet works well with 12-inch square pavers because 12 feet equals exactly 12 pavers across and 16 feet equals exactly 16 pavers down. If you choose 10-inch pavers instead, you will need to cut pavers at the edges to fill the remaining 2 inches.

Rectangular pavers (often 6 inches by 12 inches or 8 inches by 16 inches) can create running bond or herringbone patterns, but they also require more edge cuts unless your patio dimensions match the paver length. Measure your space and divide it by common paver sizes to see which one leaves the smallest remainder. The size that produces the smallest remainder is the one that will save you time and material.

Sketch Your Pattern on Paper First

Common paver patterns include running bond (pavers staggered like bricks), herringbone (pavers at 45 degrees), and basket weave (alternating direction in pairs). Each pattern looks different and requires different cuts at the edges. Draw your pattern on the same graph paper where you sketched your space, using the actual paver dimensions you chose.

As you draw, count how many pavers you need and note where cuts will occur. A herringbone pattern, for example, will have many diagonal cuts around the perimeter. A running bond pattern has fewer cuts but may look less finished. Sketch at least two patterns and compare them side by side. The pattern that requires the fewest cuts is usually the fastest to install and the cheapest in materials.

Plan for Water Drainage and Slope

Water must flow away from your house and off the patio surface. A slope of 1/8 inch per foot is standard—that means for every 4 feet away from the house, the patio drops 1/2 inch in height. On your site plan, mark the high point (closest to the house) and the low point (farthest away). This slope is gentle enough that you will not notice it when you walk, but it is steep enough to prevent pooling.

If your patio is against a house, the high point should be at the house foundation. If your patio is freestanding, choose the highest point and slope away from it in all directions. Mark the slope direction on your site plan with arrows so you remember it when you are preparing the base.

Lay Out Pavers Dry Before Digging

Place pavers on the ground in your chosen pattern without any sand or adhesive underneath. Start at a corner or the house wall and work outward, following your sketch. Leave a consistent gap between pavers—usually 1/8 inch to 1/4 inch for sand joints. Use a spacer (a piece of wood or plastic the thickness you want) to keep gaps even.

This dry run shows you exactly where cuts will fall and whether your pattern actually fits your space. You may discover that your sketch was off by an inch or that a pattern you liked on paper does not look right in person. Adjust the layout now, before you dig. Take a photo of the dry layout so you can refer to it while you work.

Mark the Layout with Chalk or Paint

Once your dry layout is correct, mark the paver positions on the ground using chalk lines or spray paint. Snap a chalk line along the outer edge of the patio perimeter. Then snap lines to mark the rows and columns of pavers, especially if you are using a grid pattern like running bond. These lines act as guides when you remove the pavers, prepare the base, and set them back in sand.

For curved edges or complex patterns, spray paint dots at key points instead of full lines. Mark the high point and low point of your slope with paint so the crew preparing the base knows which direction to slope. Label the paint marks with a marker so they are still readable after a few days of weather.

Account for Edging and Borders

Decide whether you want a border of different-colored pavers, a metal or plastic edge restraint, or pavers that straightforward end at the lawn. A border uses extra material but frames the patio and makes it look intentional. An edge restraint (aluminum or steel) keeps pavers from shifting and is invisible once grass grows over it. No border is the cheapest option but requires careful compaction at the edges to prevent movement.

If you choose a border, add it to your site plan and your material count. A 12-foot by 16-foot patio with a single-paver border on all sides needs 56 additional pavers (the perimeter) plus the interior pavers. Mark the border location on your ground layout so it is clear where the main field ends and the border begins.

Frequently Asked Questions

What if my patio space does not divide evenly by the paver size I want?

You will have a partial paver at one or more edges. Cut pavers to fit using a wet saw or angle grinder. To minimize visible cuts, center the pattern so the cut pavers are equal on opposite sides, or place the smallest cuts along the back edge farthest from the house. Avoid leaving a thin sliver (less than 2 inches) because it breaks easily.

Do I need to account for the sand joints in my measurements?

Yes, but only slightly. A 1/4-inch joint between pavers adds up over a long distance. For a 12-foot patio with 12-inch pavers and 1/4-inch joints, the joints take up about 3 inches total. Most people account for this by measuring the actual space the pavers will occupy and adjusting the edge cuts accordingly. Your dry layout will show you the exact fit.

Should I organize pavers by color or shade before I start?

If your pavers have natural color variation, sort them into light, medium, and dark shades and distribute them evenly across the patio. This prevents one area from looking darker or lighter than another. If pavers are uniform in color, organization is less critical, but grouping them by size (if you have mixed sizes) makes installation faster.

What happens if I do not slope the patio correctly?

Water pools on the surface and in the joints, which leads to algae growth, moss, and freeze-thaw damage in winter. Pooled water also makes the patio slippery. A slope of 1/8 inch per foot is gentle enough to be invisible but effective enough to drain. Mark it clearly on your layout so the person preparing the base gets it right.

Can I change my pattern after I have marked the layout?

Yes, but it is easier to change it before you mark. If you have already marked and want to switch patterns, erase or paint over the old marks and snap new lines. The dry layout is your chance to test ideas without commitment, so take your time with it and do not rush to mark until you are certain.
