Your Result Explained: Exact Takeoff Breakdown
A 10 ft × 10 ft square patio (100 square feet) is the benchmark DIY weekend project—ideal for a fire pit seating area or grill pad. Standard 4" × 8" Holland concrete or clay brick pavers measure 32 square inches each, requiring exactly 4.5 bricks per square foot. Over 100 square feet, that equals 450 pavers net.
With a 10% allowance for half-brick running-bond or herringbone end cuts, order 495 pavers (roughly 1 full pallet, as most manufacturers stack 480 to 500 four-by-eight bricks per pallet). For the foundation, 100 sq ft with 10% compaction allowance takes 1.36 cubic yards (1.89 tons, or 74 bags) of 4-inch crusher-run base, 0.34 cubic yards (19 fifty-pound bags) of 1-inch bedding sand, and 2 bags of polymeric joint sand.
For a 10×10 patio, many homeowners buy 19 bags of coarse concrete sand at the store while having the 2 tons of crusher-run base and 1 pallet of pavers delivered together.
Worked Math: 10 ft × 10 ft Patio with 4"×8" Pavers
Calculating brick count, base tonnage, and sand bags for a 100 sq ft patio with 10% waste.
- Patio Area = 10 ft × 10 ft = 100 sq ft.
- Net 4"×8" Pavers = 100 sq ft × 4.5 pavers/sq ft = 450 pavers.
- With 10% Cut Waste = 450 × 1.10 = 495 pavers.
- 4" Gravel Base (+10%) = 100 × (4 ÷ 12) × 1.10 = 36.67 cu ft = 1.36 yd³ (1.89 tons).
- 1" Bedding Sand (+10%) = 100 × (1 ÷ 12) × 1.10 = 9.17 cu ft = 0.34 yd³ (19 bags of 0.5 ft³).
- Polymeric Joint Sand = Ceiling(100 ÷ 60) = 2 bags (50 lb).
Bottom Line: Buy 495 brick pavers (4"×8"), 2 tons of crusher-run gravel base, 19 bags of 50-lb concrete sand, and 2 bags of polymeric sand.
How This Scenario Is Calculated
Why 4.5 pavers per square foot? One square foot is 12" × 12" = 144 square inches. Dividing 144 sq in by 32 sq in (4" × 8") gives exactly 4.50 pavers per square foot.
If you lay a simple straight running bond or basketweave pattern with minimal cutting, a 5% waste factor (473 pavers) is often plenty.
Pavers = Ceiling([Area (sq ft) ÷ (Paver Width × Length ÷ 144)] × (1 + Waste%)) Layer Yards = [Area (sq ft) × (Layer Depth in inches ÷ 12) × (1 + Waste%)] ÷ 27 Project-Specific Tips & Common Mistakes
Basketweave Pattern Requires Zero Saw Cuts on a 10×10 Patio
Because two 4"×8" bricks laid side-by-side form an 8"×8" square, laying a classic basketweave pattern inside a 10×10 ft (120"×120") frame requires exactly fifteen 8-inch modules in each direction with zero wet-saw cutting!
Rent a Guillotine Brick Splitter for Straight Running-Bond Cuts
If laying a running bond where every other row starts with a 4"×4" half-brick, a manual lever brick splitter snaps 4×8 pavers in two seconds with zero dust.
Mistake Using play sand in the joints between pavers instead of polymeric sand
Recommended Fix: Regular play sand blows out under leaf blowers, washes out in heavy thunderstorms, and sprouts crabgrass and ants. Sweep in polymeric sand so the polymer binder locks the joints.

Frequently Asked Questions
How much does 495 brick pavers weigh?
Each 4"×8"×2.375" concrete paver weighs about 6.2 lbs, so 495 pavers weigh approximately 3,070 lbs (1.53 tons)—exceeding the payload of a half-ton pickup truck in a single load.
How many 6x6 pavers do I need for a 10x10 patio?
A 6"×6" paver covers 0.25 sq ft (4 per sq ft), so a 10×10 patio requires 400 pavers net, or 440 pavers with 10% waste.
How many 12x12 step stones do I need for a 10x10 patio?
Since each 12"×12" paver is exactly 1 square foot, you need 100 pavers net (10 rows of 10), or 105–110 pavers to allow for any broken corners.
How many bags of paver base for a 10x10 patio if I don’t order bulk?
A 4-inch base across 100 sq ft with 10% compaction allowance equals 36.67 cubic feet, which requires 74 fifty-pound bags (0.5 cu ft each) of paver base.
Do I need landscape fabric under a 10x10 paver patio?
Yes—laying woven geotextile fabric between the native clay/soil subgrade and your 4-inch crushed stone base prevents the gravel from sinking into wet soil over time.
