Estimate patio and paving materials
Enter the area and paver size to get slab counts, sand and base quantities, plus a waste allowance.
Order once, not three times
Getting slab and base quantities right up front avoids the second delivery charge and the half-finished weekend.

Waste allowance included
Cuts at edges and breakages mean the raw area is never enough. A percentage buffer is built into the estimate.

FAQ
Perguntas frequentes
Open the web page and click the blue "New Estimate" button at the top-left to begin. Choose units (ft/in or m/mm), then add areas with the "Add Area" button where you pick a shape (Rectangle, Circle, L-shape, Custom polygon) and enter dimensions or upload a plan image via "Upload Plan (JPG/PNG/PDF)" to trace. After entering paver size (in mm or inches), joint width, and preferred pattern, press "Calculate" to get paver count, base material volumes, and a cost summary; use the "Costs" panel to update per-unit prices before finalizing.
The tool first computes the covered area from your shape and divides by the single paver area then rounds up to whole units, and includes an adjustable "Wastage" percentage in the right-hand panel (default 7% for straight patterns). If you select herringbone or diagonal patterns the default waste increases to 10–15% to account for additional cuts; you can manually set it from 0–25%. Joint width is included in the effective paver dimension calculation (input in mm or inches), and the report shows both "Exact count" (before rounding) and "Recommended purchase" (after waste and rounding).
You can upload JPG, PNG, WebP, GIF, BMP, TIFF, HEIC and PDF files up to 25 MB per file (Chrome/Firefox handle this best; Safari may convert HEICs on iOS). After uploading, click "Calibrate image" and draw a line between two known points, then enter the real-world dimension to set scale; this is required for accurate traced areas. If a PDF has multiple pages the tool reads the first vector/raster page only, and if the upload fails, use a 72–150 DPI exported PNG or a compressed PDF under 10 MB.
Yes — use the "Import CSV/XLSX" button to upload .csv or .xlsx files; accepted columns are AreaName, Shape, Length, Width, Radius, Unit (ft/m) and optionally Pattern and WastagePercent. The importer accepts up to 500 rows and a single file up to 10 MB; it validates numeric columns and reports a row-by-row preview before importing. If you use Excel save as .xlsx with headers exactly as above, and the tool will create individual areas from each row that you can edit before calculating totals.
The calculator asks for chosen base depth per area (common presets: 2", 4", 6" or in mm) and computes volume in cubic feet, cubic yards and cubic meters, rounding to two decimals. It also converts volumes into common supplier units like 50 lb sand bags and tons for crushed gravel using industry conversion factors (for example, a 50 lb bag of sand covers ~0.015 cubic yards); the output lists both volume and estimated bag/ton counts. You can switch unit preferences in the top-right "Units" menu and the report will show both imperial and metric equivalents for contractor quotes.
Open the "Costs" panel on the right side where default unit prices are prefilled (example defaults: $2.50 per sq ft for pavers, $45 per cubic yard for base material); change these to match local quotes and click "Apply Prices". The tool multiplies material quantities by unit prices, shows line-item subtotals, and includes an editable tax percentage and labor placeholder per area. You can export the detailed cost breakdown via "Download Report (PDF)" or export as CSV/Excel; currency is selectable (USD/CAD/EUR/GBP) but the calculator does not fetch live exchange rates.
The calculator works in Chrome and Firefox on desktop with full functionality; Safari and mobile browsers support basic estimating but have two limitations: iOS Safari may convert HEIC images and can run out of memory with very large plans (over ~5,000 sq ft traced), and multi-area CSV imports are slower on mobile. We recommend using a desktop for projects larger than 500 sq ft or when importing many areas. If a browser crashes, use the "Export Draft" feature before heavy edits to save a CSV of your inputs.
If you see "Invalid shape dimensions" check that numeric fields use a dot as the decimal separator (e.g., 12.5) and no thousands separators; the importer flags the exact row with an error. "File too large" means your plan image exceeded 25 MB — open it in Preview/Photoshop and export at 150 DPI or compress to under 10 MB; for calibration issues use the "Calibrate image" tool with a known measurement or draw a reference line of a door/garage width. If the page hangs in Safari, switch to Chrome or clear local storage via the browser's site settings and reload.
Calculations and plan tracing are performed client-side in your browser; uploaded files are not stored on our servers for reuse and nothing is associated with an account because there is no signup. The browser may keep session data (inputs and unsaved areas) in localStorage until you clear it or close the tab — use "Export Draft (CSV)" before closing to preserve work. If you need to share results, use the "Download Report (PDF)" or "Export CSV/XLSX" which triggers a client-side download; no external link generation or cloud storage occurs.
Use "Download Report (PDF)" to generate a printable A4 or Letter report containing area diagrams, paver counts, base volumes, and cost breakdown; the PDF is produced client-side and downloads automatically. For spreadsheet workflows press "Export CSV" or "Export XLSX" which create files with columns Area, PaversNeeded, WastagePercent, BaseCubicYards, SandBags, UnitCost, LineTotal; these import cleanly into Excel, Google Sheets, or QuickBooks. If printer scaling looks off in Safari, open the PDF in Preview (macOS) or Acrobat (Windows) and print from there with 100% scale.
Yes — export the estimate as CSV or XLSX using the "Export" menu; the exported file includes normalized columns like AreaName, Shape, PaverCount, BaseCubicYards, SandBags, GravelTons, UnitPrice, and LineTotal for each area. Those files import to Excel, Google Sheets or most job-tracking tools and can be copy-pasted into supplier order forms; the CSV format uses UTF-8 and commas, and Excel .xlsx preserves formatting for quick edits. The trade-off is this tool provides line-item quantities and cost estimates but not purchase order automation, so you’ll still need to confirm live stock and delivery with suppliers.
Use Patio Paver Calculator for quick, no-signup quantity, base-volume, and cost estimates where you need a fast material list and price plan — it gives actionable numbers in minutes. If you require precise visual layouts, 3D elevations, or cut-line optimization, export dimensions from SketchUp or CAD and import them as CSV into the calculator for accurate material totals; Photoshop or Acrobat are useful for preparing raster/PDF plans before upload (e.g., cropping, resolution adjustments). The calculator trades detailed CAD-level drafting for speed and straightforward purchasing data, so combine tools when you need both accurate visuals and exact quantities.
