Paver Calculator
Paving a patio, walkway, or driveway requires careful planning. Estimating the number of pavers, base material, and sand can be confusing. The Paver Calculator is an intuitive tool designed to simplify these calculations and save time, money, and materials.
This calculator provides:
- Number of pavers required (with and without waste)
- Total cost of pavers
- Base material volume and cost
- Sand for joints
- Total material cost
It works for rectangles, circles, and triangles, and supports custom paver sizes and gaps.
How the Paver Calculator Works
Step 1: Choose Your Project Shape
Select from Rectangle, Circle, or Triangle. The calculator will adjust the input fields accordingly:
- Rectangle → Length × Width
- Circle → Radius
- Triangle → Base × Height
Step 2: Enter Paver Dimensions and Gap
Input the paver length and width in inches. Include the gap size between pavers (default 0.25 inches) to account for spacing.
Step 3: Enter Waste Factor
A waste factor accounts for broken or cut pavers and design adjustments. Default is 10%, adjustable as needed.
Step 4: Input Material Costs
Enter the price per paver and base material price per cubic yard.
Step 5: Click “Calculate”
The calculator will display:
- Project area (sq ft)
- Paver area (including gap)
- Pavers needed (with and without waste)
- Paver cost
- Base material volume and cost
- Sand for joints
- Total material cost
Example Calculation
Inputs:
- Project Shape: Rectangle
- Length: 20 ft
- Width: 15 ft
- Paver: 12" × 6"
- Gap: 0.25 inches
- Waste Factor: 10%
- Paver Price: $1.50
- Base Material: $40 per cu yd
Results:
- Project Area: 300 sq ft
- Paver Area (with gap): 0.521 sq ft
- Pavers Needed (No Waste): 576
- Pavers Needed (With Waste): 634
- Pavers Cost: $951
- Base Material Needed: 44.44 cu yd
- Base Cost: $1,780
- Sand Needed: 450 lbs
- Total Material Cost: $2,731
This shows how proper planning reduces waste and ensures you purchase the correct amount of materials.

Frequently Asked Questions (FAQs)
1. How is the number of pavers calculated?
The calculator divides the project area by the paver area including the gap, then applies a waste factor.
2. Can I use custom paver sizes?
Yes, enter the length and width in inches. The calculator accommodates any size.
3. What is the waste factor?
It accounts for broken or cut pavers and design adjustments. Default is 10%, adjustable up to 50%.
4. How is the base material calculated?
A 4-inch base layer is assumed. The volume is calculated in cubic feet and converted to cubic yards.
5. Does it include sand for joints?
Yes, the calculator estimates sand needed for filling gaps between pavers.
6. Can I calculate circular and triangular projects?
Yes, it supports rectangles, circles, and triangles with appropriate input fields.
7. How do gaps affect the number of pavers?
Adding gaps increases the effective paver area slightly, reducing the number of pavers required.
8. Can this be used for large commercial projects?
Yes, the calculator works for both residential and commercial projects as long as accurate dimensions are entered.
9. How do I estimate total cost?
The calculator multiplies pavers needed by price and adds base material cost for total materials.
10. Can I reset the calculator?
Yes, click the Reset button to clear all inputs.
11. How accurate is the calculation?
Accuracy depends on precise project measurements and correct paver size input. Always round up slightly to ensure sufficient material.
12. What if my project has irregular shapes?
Divide the project into rectangles, triangles, or circles, calculate each area, and sum them.
13. Can I adjust base depth?
The default is 4 inches. For heavier loads or driveways, a deeper base may be required, and the base material cost should be adjusted accordingly.
14. Can I include paver spacing in calculations?
Yes, the gap size input accounts for spacing between pavers.
15. Why does the sand estimate use lbs instead of volume?
Sand for joints is calculated in pounds based on the project area, which is a common way suppliers provide material for filling gaps.
This Paver Calculator is a simple, reliable tool to ensure your paving project stays on budget, minimizes waste, and avoids overbuying.
