Estimating Materials Needed For Your Paver Patio

mathematical formulas to calculate the materials needed for a patio

Welcome to a comprehensive toolkit of precision, brought to you by none other than Three Timbers, the beacon of landscaping expertise. A rising titan in the industry, our endeavor has always been twofold – empowering our hardworking team and enlightening our esteemed clients. While our experts execute perfection on-site using this guide, our clients can dive deep into our processes, and even embark on their own DIY paving adventures.


Getting the foundation right is the cornerstone of any great project.

Project Blueprint: Let’s take a 10′ × 15′ Rectangular patio with a 6″ base as an example.

  • Begin by calculating the patio’s square footage.
  • Now, divide that square footage by 200 (since a ton of loose aggregate covers 200 SqFt at a thickness of 1″).
  • Multiply by the base thickness (in inches).
  • To account for compaction, multiply by 1.25.

Voila, you have the tons of aggregate you’ll need.

Example in Action:

Given the dimensions, the total square footage equals 150 SqFt.

Here’s the math: 

150 ÷ 200 = 0.75 tons for every inch of base. 

0.75 tons x 6 inches = 4.5 tons. 

Adjusting for compaction: 4.5 x 1.25 = 5.625. 

Total Aggregate Needed: 5.625 tons.


This plays a pivotal role in paving projects.

Project Blueprint: Using the same 10′ x 15′ patio, with a 6″ base:

  • Begin with the square footage.
  • Divide by 200 (since 1 ton of loose aggregate suffices for 200 SqFt at 1″ thickness).
  • Multiply by the sand’s thickness in inches.
  • Lastly, multiply by 1.25 to account for compaction.

Example in Action:

For 150 SqFt: 

150 ÷ 200 = 0.75 tons for every inch of base. 

0.75 x 1 inch of sand = 0.75 tons. 

Accounting for compaction: 0.75 x 1.25 = 0.9375.

Total Bedding Sand Needed: 0.9375 tons.


Elegant boundaries can transform a space.

Project Blueprint: For a 10’x 15′ patio using Holland Stone:

  • Measure the total linear footage.
  • Convert it to inches by multiplying by 12.
  • Divide by the width of the stone for the number of stones needed.
  • Multiply the units by the SqFt/Unit.

Example in Action:

Total linear footage = 50 LnFt.

Converted to inches: 50 x 12 = 600. 

600 ÷ 4 (assuming width of the stone) = 150 units. 

Total square footage: 150 x .215 = 32.25. 

Total Square Footage Needed: 32.25 SqFt.


It’s all about the elongated, graceful boundaries.

Project Blueprint: For the same 10’x 15′ patio, using Holland Stone:

  • Again, start with the total linear footage.
  • Convert to inches.
  • Divide by the stone’s length to determine the units required.
  • Finally, calculate the SqFt needed.

Example in Action:

Total linear footage = 50 LnFt.

600 inches ÷ 8 (assuming length of stone) = 75 units. 

Square footage required: 75 x .215 = 16.125. 

Total Square Footage Needed: 16.125 SqFt.
