Your Result Explained: Exact Takeoff Breakdown
A 12 ft × 16 ft patio (192 square feet) comfortably fits a 6-person outdoor dining table and grill station. Using popular 6" × 9" rectangular patio pavers (2.67 pavers per sq ft), the net area takes 512 pavers; adding a 10% allowance for border cuts and culling brings your order to 564 pavers (approx. 5,900 lbs or 2.95 tons of stone).
Beneath those pavers, a 4-inch compacted crusher-run sub-base with 10% compaction allowance requires 70.40 cubic feet—equal to 2.61 cubic yards or 3.65 short tons. The 1-inch screeded concrete sand layer requires 17.60 cubic feet—equal to 0.65 cubic yards (0.88 tons, or 36 fifty-pound sand bags)—plus 4 bags of polymeric joint sand.
Because the gravel base (3.65 tons), bedding sand (0.88 tons), and pavers (2.95 tons) total roughly 7.5 tons of material, always schedule bulk dump delivery for the aggregate and forklift pallet delivery for the pavers.
Worked Takeoff: 16 ft × 12 ft Patio (192 Sq Ft) with 10% Overage
Full three-layer calculation for a 192 sq ft patio using 6"×9" pavers, 4" gravel base, and 1" sand bed.
- Patio Area = 16 ft × 12 ft = 192 sq ft.
- 6"×9" Pavers (2.667/ft²) = 192 × 2.6667 × 1.10 = 563.2 → 564 pavers.
- 4" Gravel Base Volume = 192 × (4 ÷ 12) × 1.10 = 70.40 cu ft = 2.61 yd³.
- Gravel Base Tonnage (at 1.40 t/yd³) = 2.61 × 1.40 = 3.65 tons.
- 1" Bedding Sand Volume = 192 × (1 ÷ 12) × 1.10 = 17.60 cu ft = 0.65 yd³ (36 bags).
- Polymeric Joint Sand = Ceiling(192 ÷ 60) = 4 bags (50 lb).
Bottom Line: Order 564 pavers (6"×9"), 3.75 to 4 tons of crusher-run gravel, 1 cubic yard (or 36 bags) of concrete sand, 4 bags of polymeric sand, and 56 linear feet of paver edging.
How This Scenario Is Calculated
If you choose classic 4"×8" brick pavers (4.5 per sq ft) instead of 6"×9" pavers, your paver count changes to 864 net (951 with 10% waste), while your gravel base and bedding sand quantities remain identical.
Remember to excavate to 7.38 inches deep (4" base + 1" sand + 2.38" paver) and slope the subgrade 1/4 inch per foot (3 inches over the 12-foot width) away from the house.
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
Order 4 Full Tons of Base Gravel to Cover the 6-Inch Border Extension
Extending the 4-inch gravel base 6 inches outside the 12×16 paver perimeter creates a 13×17 ft base footprint (221 sq ft), which uses right at 4.0 tons of compacted crusher run.
Rent a 180-Lb Plate Compactor for One Full Day
You will use the plate compactor twice: first to compact the crusher-run gravel base in two 2-inch lifts, and second (with a rubber pad or piece of carpet tied under the plate) to seat the pavers into the screeded sand.
Mistake Compacting pavers AFTER sweeping in polymeric sand without vibrating first
Recommended Fix: Seat the pavers into the bedding sand with a plate compactor first, then sweep in polymeric sand and vibrate a second time so joints pack from bottom to top.

Frequently Asked Questions
How many 12x12 patio blocks do I need for a 12x16 patio?
Since each 12" × 12" slab covers 1.0 square foot, a 12×16 patio takes 192 blocks net, or 212 blocks with a 10% allowance for breakage and cuts.
How much dirt will I dig out for a 12x16 paver patio?
Excavating 192 sq ft to a depth of 7.5 inches generates 120 bank cubic feet (4.44 cubic yards) of soil, which fluffs up by ~25% when dug to about 5.5 cubic yards (6 tons) of loose dirt.
How many linear feet of paver edging do I need for a 12x16 patio?
The full perimeter is 12 + 16 + 12 + 16 = 56 linear feet. If one 16-foot side butts directly against your house foundation, you need 40 linear feet of edging (five 8-foot strips) and about 40 ten-inch landscape spikes.
Can I use leveling panels (Brock PaverBase) instead of 4 inches of gravel?
High-density polypropylene paver base panels can replace ~3.5 inches of stone on flat, pedestrian-only patios over well-drained soil, though you still need 1/2 to 1 inch of leveling sand underneath the panels.
How long does it take two DIYers to build a 12x16 paver patio?
Allow one full weekend: Day 1 for excavation and compacting the 4-inch gravel base, and Day 2 for screeding sand, laying the 564 pavers, spiking edging, and sweeping polymeric sand.
