Quartz 10 ft run: 22.08 sq ft, $2,870.83, 397.50 lb, 1 slab. The standard depth is 25 in. Enter your run length, depth, overhang, and material to work out yours.
Countertops come in standard depths and thicknesses, and the cost and the weight both follow the area. This chart lists the eight common materials with their cost and weight per square foot, and works out the finished depth, area, cost, weight, and slabs for your kitchen run.
The standard countertop depth is 25 in: the common rule is a 24 in base cabinet plus a 1 in overhang, and 25 in is the standard slab depth. The thickness depends on the material: laminate, butcher block, concrete, and stainless steel are usually 1.5 in thick, granite, quartz, and marble are usually 1.25 in, and solid surface is usually 0.75 in. The chart below lists the eight common materials with their standard depth, thickness, cost per square foot, and weight per square foot. The cost is a range, because the price depends on the colour, the edge profile, and the region; the tool uses the midpoint of each range, so the cost it shows is a mid-range estimate, not a quote. The weight matters because a stone countertop is heavy: quartz weighs 18 lb per square foot, so a 10 ft run weighs nearly 400 lb, and the cabinets underneath have to carry it.
| Material | Standard depth | Thickness | Cost per sq ft | Midpoint | Weight per sq ft |
|---|---|---|---|---|---|
| Laminate | 25 in | 1.5 in | $20–50 | $35.00 | 6 lb/sq ft |
| Butcher block | 25 in | 1.5 in | $40–100 | $70.00 | 6 lb/sq ft |
| Solid surface | 25 in | 0.75 in | $50–120 | $85.00 | 6 lb/sq ft |
| Granite | 25 in | 1.25 in | $50–200 | $125.00 | 18 lb/sq ft |
| Quartz | 25 in | 1.25 in | $60–200 | $130.00 | 18 lb/sq ft |
| Marble | 25 in | 1.25 in | $75–250 | $162.50 | 17 lb/sq ft |
| Concrete | 25 in | 1.5 in | $80–200 | $140.00 | 19 lb/sq ft |
| Stainless steel | 25 in | 1.5 in | $100–200 | $150.00 | 10 lb/sq ft |
At the default — a 10 ft run, 25 in deep, 1.5 in overhang, quartz — the finished depth is 26.50 in, the area is 22.08 sq ft, the cost is $2,870.83 (at $130.00 a square foot), the weight is 397.50 lb, and it takes 1 slab.
The finished depth is the countertop depth plus the overhang: 25 in + 1.5 in = 26.50 in. The area is the run length in feet times the finished depth in inches divided by 12: 10 × 26.50 / 12 = 22.08 sq ft. The cost is the area times the material’s midpoint cost per square foot: 22.08 × $130.00 = $2,870.83. The weight is the area times the material’s weight per square foot: 22.08 × 18 = 397.50 lb. The slabs are the area divided by 55.125 and rounded UP: a standard slab is 126 × 63 in, which is 55.125 sq ft, so 22.08 / 55.125 = 0.40, which rounds up to 1 slab. The rounding is always up, never to the nearest whole number, because a short slab is useless: you cannot buy four-tenths of a slab.
Setup: run length 10 ft, countertop depth 25 in, overhang 1.5 in, material quartz at $130.00 a square foot and 18 lb a square foot.
Line 1 — the finished depth. 25 + 1.5 = 26.50 in.
Line 2 — the area. 10 × 26.50 / 12 = 22.08 sq ft.
Line 3 — the cost. 22.08 × $130.00 = $2,870.83.
Line 4 — the weight. 22.08 × 18 = 397.50 lb.
Line 5 — the slabs. 22.08 / 55.125 = 0.40, rounded up = 1 slab.
Reverse: a $3,000 budget buys 23.08 sq ft of quartz ($3,000 / $130.00), which is a 10.45 ft run at 26.50 in finished depth. An area of 30 sq ft needs a 13.58 ft run at the same depth. A 36 × 72 in island is 18.00 sq ft and costs $2,340.00 in quartz.
12 ft run, quartz: the area is 26.50 sq ft, the cost is $3,445.00, the weight is 477.00 lb, and it takes 1 slab. Two more feet of run add $574.17 and 79.50 lb.
30 in depth (island), quartz: the finished depth is 31.50 in, the area is 26.25 sq ft, the cost is $3,412.50, the weight is 472.50 lb, and it takes 1 slab. A deeper countertop costs more per foot of run, because every foot of run covers more square feet.
Laminate, 10 ft: the area is still 22.08 sq ft — the area does not depend on the material — but the cost is $772.92 and the weight is 132.50 lb, and it takes 1 slab. Laminate is the cheapest material in the chart and the joint-lightest.
Marble, 10 ft: the area is still 22.08 sq ft, the cost is $3,588.54 and the weight is 375.42 lb, and it takes 1 slab. Marble is the dearest material in the chart at $162.50 a square foot.
Granite, 10 ft: the area is still 22.08 sq ft, the cost is $2,760.42 and the weight is 397.50 lb, and it takes 1 slab. Granite weighs the same as quartz at 18 lb a square foot, but costs $5.00 less per square foot at the midpoint.
8 ft run, quartz: the area is 17.67 sq ft, the cost is $2,296.67, the weight is 318.00 lb, and it takes 1 slab. A shorter run still takes a whole slab: the slab count only changes when the area passes 55.125 sq ft.
30 ft run, quartz: the area is 66.25 sq ft, the cost is $8,612.50, the weight is 1,192.50 lb, and it takes 2 slabs. 66.25 / 55.125 = 1.20, which rounds up to 2: the second slab is mostly offcut, which is why long runs waste more stone.
Reverse — the other way round: a $3,000 budget buys 23.08 sq ft of quartz, a 10.45 ft run; an area of 30 sq ft needs a 13.58 ft run; a 36 × 72 in island is 18.00 sq ft and costs $2,340.00 in quartz.
The chart assumes the standard depths and thicknesses above, a plain rectangular run with no cutouts, no sink, and no cooktop, and a standard slab of 126 × 63 in (55.125 sq ft). It assumes the cost is the midpoint of each material’s range, so the cost it shows is a mid-range estimate: the real price varies by region, by colour, and by edge profile, and it leaves out templating, fabrication, delivery, and installation. It does not allow for waste, seams, or offcuts: a run that needs 1.2 slabs still buys 2, and the offcut is not free. With a run length of 0, the area is 0.00 sq ft and the cost is $0.00. With an overhang of 0, the finished depth is 25.00 in, the area is 20.83 sq ft, and the quartz cost is $2,708.33. This is a size, cost, and weight reference, NOT a fabrication, templating, or structural-load chart: it does not say whether your cabinets can carry the weight, whether the slab can be cut to fit, or how the seams will fall. Rounding convention: totals are computed from unrounded values, so rounded parts may differ by a cent from their rounded sum; slabs are always rounded up, never to the nearest whole number.

| Finished depth | depth + overhang | 26.50 in. |
| Area | run length × finished depth / 12 | 22.08 sq ft. |

The math is exact for the numbers you enter: the finished depth is the depth plus the overhang, the area is the run length times the finished depth divided by 12, the cost is the area times the material’s midpoint, the weight is the area times the weight per square foot, and the slabs are the area divided by 55.125 and rounded up. What the chart cannot do is price your real kitchen: check the material, because the cost range is wide — quartz runs $60–200 a square foot — and the midpoint is only the middle of the range. It assumes a plain rectangular run with no cutouts, no sink, and no cooktop, a standard slab of 126 × 63 in, and the standard depths and thicknesses above. It leaves out templating, fabrication, delivery, installation, waste, seams, and offcuts. It is a size, cost, and weight reference, not a fabrication, templating, or structural-load chart.

Bright Side Kit. "Countertop Size Chart: Dimensions, Cost & Weight 2026" https://brightoolbox.com/countertop-size-chart/ Accessed October 25, 2026.$2,870.83. A 10 ft run at 25 in deep with 1.5 in overhang is 26.50 in finished depth and 22.08 sq ft, and quartz costs $130.00 a square foot at the midpoint. It weighs 397.50 lb and takes 1 slab.
25 in. The common rule is a 24 in base cabinet plus a 1 in overhang, and 25 in is the standard slab depth. With the default 1.5 in overhang the finished depth is 26.50 in.
Divide the area by 55.125 and round up. A standard slab is 126 × 63 in, which is 55.125 sq ft. A 22.08 sq ft run takes 1 slab, and a 66.25 sq ft run takes 2 slabs, because 66.25 / 55.125 = 1.20 and the count always rounds up.
Laminate, at $35.00 a square foot at the midpoint. A 10 ft run costs $772.92 in laminate against $3,588.54 in marble, the dearest material in the chart. Laminate and butcher block are also the lightest, at 6 lb a square foot.
18.00 sq ft, and $2,340.00 in quartz. A 36 × 72 in island is 2,592 sq in, which is 18.00 sq ft. It fits in one slab, with room to spare.
23.08 sq ft — a 10.45 ft run at 26.50 in finished depth. Quartz costs $130.00 a square foot at the midpoint, so $3,000 / $130.00 = 23.08 sq ft. An area of 30 sq ft needs a 13.58 ft run.
