Your Result Explained: Exact Takeoff Breakdown
A 3-foot-wide by 30-foot-long front walkway (90 square feet) is wide enough for comfortable single-file walking while keeping excavation manageable. Note that on narrow paths, border cuts represent a larger percentage of the total stone count than on wide square patios, so a 10% waste allowance is essential. Using 4" × 8" brick pavers (4.5 per sq ft), 90 sq ft requires 405 net pavers, or 446 pavers with 10% overage.
For the walkway trench, a 4-inch compacted crusher-run sub-base (+10% compaction) requires 33.00 cubic feet—equal to 1.22 cubic yards or 1.71 short tons (66 fifty-pound bags). The 1-inch screeded concrete sand layer requires 8.25 cubic feet—equal to 0.31 cubic yards or 17 fifty-pound bags—plus 2 bags of polymeric jointing sand.
Don’t forget edge restraint: unlike a square 10×10 patio (which has 40 ft of perimeter), a long 3×30 walkway has 60 linear feet of side borders (30 ft on the left + 30 ft on the right), requiring eight 8-foot strips of paver edging.
Worked Math: 30 ft × 3 ft Walkway (90 Sq Ft) Takeoff
Computing pavers, aggregate base, bedding sand, and edging for a 3×30 ft garden path.
- Walkway Area = 30 ft × 3 ft = 90 sq ft.
- 4"×8" Pavers (+10% Waste) = 90 × 4.5 × 1.10 = 445.5 → 446 pavers.
- 4" Gravel Base (+10%) = 90 × (4 ÷ 12) × 1.10 = 33.00 cu ft = 1.22 yd³ (1.71 tons).
- 1" Bedding Sand (+10%) = 90 × (1 ÷ 12) × 1.10 = 8.25 cu ft = 0.31 yd³ (17 bags).
- Polymeric Joint Sand = Ceiling(90 ÷ 60) = 2 bags (50 lb).
- Side Edging Restraint = 30 ft × 2 sides = 60 linear feet (8 × 8-ft strips).
Bottom Line: Order 446 brick pavers, 1.75 to 2.0 tons of crusher-run base, 17 bags of coarse concrete sand, 2 bags of polymeric sand, and 60 linear feet of paver edging.
How This Scenario Is Calculated
Every 10 linear feet of a 3-foot-wide walkway equals 30 square feet—requiring 135 net 4"×8" bricks (149 bricks with 10% waste) and 0.57 tons of 4-inch gravel base.
If you widen the front entry walk from 3 feet to 4 feet (so two people can walk side-by-side), area increases by 33% to 120 square feet (594 pavers and 2.28 tons of base gravel).
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
Dig the Walkway Base Trench 4 Feet Wide for a 3-Foot Path
Because both long sides of a walkway border open lawn, dig the gravel trench 48 inches wide (6 inches wider on both sides) so your 60 linear feet of plastic edging spikes anchor into solid compacted stone.
Lay a Soldier Course Border Along Both Edges
Running a row of 4"×8" bricks perpendicular along both outer edges ("soldier course") frames the walkway visually and locks curved path edges against lateral movement.
Mistake Making a primary front-door walkway narrower than 36 inches
Recommended Fix: Paths under 36 inches feel cramped when carrying groceries or luggage; 36 inches (3 ft) is the practical minimum for secondary paths and 42 to 48 inches is ideal for main front entries.

Frequently Asked Questions
How many 12x12 pavers for a 3x30 walkway?
A 3-foot-wide by 30-foot-long path is exactly 3 rows wide by 30 blocks long = 90 twelve-by-twelve pavers net (buy 95–100 to have spares).
Should a paver walkway be crowned in the middle or sloped to one side?
Tilting (cross-sloping) the entire walkway 1/8 to 1/4 inch per foot toward the downhill lawn side (~1/2 inch drop across a 3-foot width) is much easier to screed flat than building a center crown.
How many landscape spikes do I need for 60 feet of walkway edging?
Drive one 10-inch steel spiral spike every 12 inches on straight runs (and every 6–8 inches on curves), which equals 60 to 75 spikes for a 30-foot walkway.
Can I curve a 3x30 walkway using rectangular 4x8 pavers?
Yes—gentle sweeping curves can be laid by slightly fanning the joints or cutting wedge-shaped miters along the inside curve with a diamond blade on an angle grinder or wet saw.
How much gravel and sand for a 4x30 foot walkway?
A 4×30 walkway (120 sq ft) with 10% overage requires 594 four-by-eight pavers, 1.63 cubic yards (2.28 tons) of 4-inch gravel base, and 22 fifty-pound bags of 1-inch bedding sand.
