Deck Tiles: Measure Your Project and Order the Right Quantity

Start with Accurate Project Dimensions

Before selecting any materials, measure the length and width of the area where you plan to install deck tiles. Use a tape measure and record dimensions in feet and inches. For rectangular or square areas, measure at multiple points to confirm the space is consistently shaped. If your area is irregular, break it down into smaller, manageable rectangles or squares. Sketching your project area and noting these dimensions will be invaluable for the next steps.

Consider any fixed obstacles within the area, such as columns, planters, or built-in seating. These will affect your tile layout and require specific cuts. Measure their positions relative to the edges of your project area.

Choosing Your Deck Tile Size

Lumber Plus offers deck tiles in two primary sizes: 12 x 12 inches and 24 x 24 inches. Each size offers different aesthetic and practical considerations for your project.

The 12 x 12 inch tile is a compact square format, covering 1 square foot per tile. This size can be suitable for smaller areas, balconies, or layouts with many edges, curves, or transitions, as it allows for more detailed fitting and potentially less waste on intricate cuts. For example, a narrow balcony might benefit from the smaller module to minimize cuts along its length.

The 24 x 24 inch tile is a larger square format, covering 4 square feet per tile. This size is often chosen for larger terraces and open surfaces where fewer tile seams are desired. It can create a sense of expanse and reduce the overall number of modules to handle during installation. However, larger tiles may result in more waste when cutting around small or complex obstacles.

Available species include Ipe, Garapa, and Cumaru, each offering distinct colors and grain patterns. Ipe provides deep chocolate tones, Garapa features warm golden tones, and Cumaru has rich reddish-brown hues.

Consider how the tile size will visually impact your space and how it will interact with the overall dimensions. A larger tile might make a small space feel cramped, while a smaller tile might create a busy pattern on a vast terrace.

Calculating Base Quantity: Area and Coverage

Once you have your project dimensions and selected tile size, you can calculate the base quantity needed. This initial calculation assumes no cuts and full tile coverage.

For a rectangular area, multiply the length by the width to get the total square footage. For example, a patio measuring 10 feet by 12 feet has an area of 120 square feet.

If you choose 12 x 12 inch deck tiles (1 square foot per tile), you would initially need 120 tiles (120 sq ft / 1 sq ft per tile).

If you choose 24 x 24 inch deck tiles (4 square feet per tile), you would initially need 30 tiles (120 sq ft / 4 sq ft per tile).

This is a starting point. The actual number of tiles required will likely be higher due to cuts and a waste factor.

Accounting for Cuts and Waste: A Practical Example

Rarely will your project dimensions perfectly align with whole deck tile modules. Most projects require tiles to be cut to fit edges, around obstacles, or to create specific patterns. This means you will need to purchase more tiles than your base area calculation suggests.

A common industry practice is to add a waste factor to your initial tile count. This factor typically ranges from 5% to 15%, depending on the complexity of your layout and the amount of cutting involved. For a simple rectangular area with minimal cuts, 5% might suffice. For irregular shapes, multiple obstacles, or complex patterns, 10% to 15% is a more prudent estimate.

Let's consider a hypothetical balcony measuring 8 feet 6 inches (8.5 feet) by 10 feet 0 inches (10 feet). You plan to use 24 x 24 inch (2-foot x 2-foot) deck tiles. The total area is 8.5 ft * 10 ft = 85 square feet.

Each 24 x 24 inch tile covers 4 square feet. The base calculation would be 85 sq ft / 4 sq ft per tile = 21.25 tiles. Since you cannot purchase a quarter tile, you would round up to 22 tiles for the base coverage.

Now, let's consider the layout. Along the 10-foot length, you will need 5 full tiles (10 ft / 2 ft per tile). Along the 8.5-foot width, you will need 4 full tiles (8 ft / 2 ft per tile) and then a partial tile that is 0.5 feet (6 inches) wide.

This means for each 10-foot row, you will lay 4 full 24-inch tiles and then cut a 24-inch tile down to 6 inches for the remaining width. Each cut tile will result in a 6-inch piece and an 18-inch offcut. If the offcut is not large enough or suitable for reuse in another part of the project, it contributes to waste.

For this 8.5 ft by 10 ft balcony, a visual grid might look like this:

Row 1: 5 full tiles (24"x24")

Row 2: 5 full tiles (24"x24")

Row 3: 5 full tiles (24"x24")

Row 4: 5 full tiles (24"x24")

Row 5 (partial width): 5 tiles cut to 6"x24". This requires 5 full 24"x24" tiles to be cut.

Total full tiles needed for the first 4 rows: 4 rows * 5 tiles/row = 20 tiles.

Total tiles needed for the 5th (partial) row, assuming each cut creates an unusable offcut: 5 tiles.

Total tiles for this layout: 20 + 5 = 25 tiles.

Comparing this to the base calculation of 22 tiles, the actual layout requires 3 additional tiles due to cuts. This represents a waste factor of approximately 13.6% (3 tiles / 22 tiles).

For a simpler waste estimate, applying a 10% waste factor to the 22 base tiles would suggest ordering 22 * 1.10 = 24.2 tiles, rounded up to 25 tiles. This demonstrates how a waste factor helps approximate the additional material needed for cuts.

Finalizing Your Order Quantity

After calculating your base quantity and considering a waste factor, you should have a solid estimate for your deck tile order. Always round up to the nearest whole tile, as tiles are sold in full units.

It is generally advisable to order a few extra tiles beyond your calculated total. This provides a small buffer for unexpected breakage, miscuts, or future repairs. Having a few spare tiles on hand can save time and effort if a replacement is needed down the line, especially if the exact product run is no longer available.

Consider the layout patterns you plan to use. Straight lay patterns typically have less waste than diagonal patterns. If you are creating a multi-species pattern, ensure you calculate quantities for each species separately and apply the waste factor to each.

Before you order

• Measure your project area accurately, noting length, width, and any fixed obstacles.
• Sketch your layout, indicating tile placement and areas requiring cuts.
• Choose your preferred deck tile size (12x12 or 24x24 inches).
• Calculate the total square footage of your project area.
• Divide the total square footage by the area per tile to get your base tile count.
• Determine a suitable waste factor (5-15%) based on layout complexity and add it to your base tile count.
• Round up to the nearest whole tile for your final order quantity.
• Consider ordering a few extra tiles for future repairs or contingencies.

Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.
