Pool Coping 4x9

4x9 pool coping is the smallest cap we cut: 4" deep, 9" along the water, 1-1/4" thick, in bullnose and remodel (drop-face) profiles. It is available in marble and travertine and sold by the pallet or by the piece. Radius, layout and profile notes are below the products.

Where 4x9 pool coping earns its place on a pool

A 4x9 piece covers 0.75 linear feet of pool edge, so a 100 ft perimeter takes roughly 134 pieces before overage. That sounds like a lot of joints, and it is the whole point: with only 9" between joints, the cap can follow a tight radius, a kidney pool, a raised spa wall or a sun shelf without the corners of each piece sticking out past the curve. A 12x24 cap will not bend around a 4 ft radius; a 4x9 will. The 4" depth is a deliberate trade: it caps a narrow bond beam and leaves the deck pavers to run almost to the water.

Profiles, thickness and what it lays with

Every product here is 1-1/4" thick. Roughly half are bullnose for new construction and half are remodel coping with the drop-face lip that hides an old cantilever edge. In marble it comes leather or sandblasted in Ice White, Ibiza White, Bursa White, Corsica Cream, Tundra Grey, Diane Royal and Ocean Blue; the travertine options are Ivory, Walnut, Noce, Silver and Country Classic. Because 9" divides evenly into 18" and 36", the joints line up with a 6x12 paver field every other course, or you can leave a soldier course between. For the step up to 1 linear foot per piece, see 6x12 coping, and for the full lineup start at pool coping. Our coping size guide shows the radius each size can handle.

Frequently asked questions

How many 4x9 coping pieces do I need per linear foot?

Each 4x9 piece runs 9 inches along the pool edge, which is 0.75 linear feet, so you need about 1.33 pieces per linear foot. Measure the full perimeter, divide by 0.75, then add 10 to 15 percent for cuts around returns and radius sections.

Is 4x9 coping available in 2 inch thickness?

No. Everything in this collection is 1-1/4 inch thick. If you want a 2 inch cap on a freeform pool, the next size up, 6x12, is available in both 1-1/4 inch and 2 inch and still handles curves well.

Which profile should I pick, bullnose or remodel?

Bullnose is the rounded front edge for new pools and full tear-outs. Remodel coping has a drop-face lip that hangs over the old beam edge, so it is the choice when you are resurfacing an existing pool without removing the original cantilever.
