Paver calculator square feet
Plan your paving with confidence. This calculator combines standard area estimation with a statistical layer: use sample measurements of your pavers to get a range (confidence interval) for the total number needed. Everything stays in square feet, inches, and simple percentages.
Interactive paver calculator
Fill in your project dimensions, paver size, and — if you have them — sample measurements. Then click calculate.

Understanding your inputs
Every number you enter plays a role. The table below explains each field.
- Length/width (ft): total paved area dimensions.
- Paver size + joint: effective size = paver + joint width.
- Waste %: extra for cutting & breakage.
- Sample data: measured lengths/widths to capture real‑world variation.
- Confidence level: probability that true mean falls inside interval.
- Model year: your reference (2024,2025…).
| Field | Interpretation |
|---|---|
| Length, width (ft) | Rectangle area; if shape is irregular, use average length/width. |
| Paver L × W (in) | Nominal dimensions before joint. |
| Joint (in) | Gap between pavers – added to effective size. |
| Sample lengths/widths | Comma‑separated numbers (at least two for statistics). |
| Confidence level | 90%,95%,99% – higher = wider interval. |
Basic calculation results explained
After clicking calculate, you get two main numbers: area and nominal pavers (assuming perfect paver size).
- Area (sq ft): length × width.
- Nominal pavers: area ÷ effective area per paver × (1 + waste/100).
| Metric | Formula / note |
|---|---|
| Area (sq ft) | — |
| Effective paver (sq ft) | — |
| Pavers per sq ft | — |
| Nominal count | — |
Statistical confidence intervals
Based on your sample, we compute a range for the mean paver area, then translate that into a range for total pavers. This accounts for uncertainty in paver dimensions.
- Lower/upper pavers: interval for number of pavers (includes waste).
- CI for mean length/width: shows variability in sample.
| Parameter | Value ± margin |
|---|---|
| Mean length (in) | - |
| Mean width (in) | - |
| Mean paver area (sq ft) | - |
| Pavers CI (lower – upper) | - |
Sample data summary
Descriptive statistics from your sample lengths and widths.
- Sample size, mean, standard deviation, standard error.
- If only one sample type is given, the other dimension is treated as fixed.
| Variable | n | Mean (in) | SD (in) | SE (in) |
|---|---|---|---|---|
| Length | - | - | - | - |
| Width | - | - | - | - |
Model year relevance
The model year you choose (e.g., 2024, 2025, 2026) is recorded for your project records. It doesn’t affect math, but helps distinguish paver batches or design updates.
- Use any year: past, present, future.
- Handy for multi‑phase projects.
| Selected year | Purpose |

| 2025 | Reference for paver model / batch |
