Sintered stone 240 x 120 cm: size, weight and uses
Short answer: one 240 x 120 cm slab covers 2.88 m2. The common thickness is 9 mm, one slab weighs about 62 kg, and market price runs from Rp 1.800.000 to Rp 2.100.000 per slab.
The numbers that matter
| Item | Value | Used for |
|---|---|---|
| Size | 240 x 120 cm | maximum panel without a join |
| Area per slab | 2.88 m2 | calculating slab count |
| Common thickness | 9 mm | stiffness and support |
| Weight per slab | 62 kg | lifting and cabinet load |
This is the economical format, one slab is enough for a table or a splashback.

Working out how many slabs
Divide the panel area by 2.88 m2 and round up. A 3 m worktop at 60 cm is 1.8 m2, so one slab covers it. An island with two visible faces doubles that, and the offcut decides whether one slab is still enough.
What gets missed: splashbacks, visible end panels, and spare material for cutting mistakes. Add 10 to 15 percent before ordering.

When this format saves money
The 240 x 120 cm format makes sense when no panel is wider than 2.4 m. For a domestic worktop that is the common case, and the offcut still covers a splashback or a vanity top.
| Job | Requirement | Note |
|---|---|---|
| Worktop 2.4 m x 60 cm | 1 slab | No join in the working surface |
| Worktop 3 m x 60 cm | 2 slabs | Join in the middle, vein direction must be set |
| Splashback 3 m x 60 cm | 1 slab | Can come from the worktop offcut |
| Vanity 1.2 m x 50 cm | 1 slab | Large offcut left for other surfaces |
What makes this format economical is the thickness. The 9 mm version uses less material than 12 mm, and on a supported top the difference in stiffness is rarely felt in a home.
The trade-off is the join. At 240 cm, a three metre worktop almost always needs one, and a join in the middle of the working surface collects dirt more than a join at the end.
Buyer questions
Short answers for buyers comparing looks, formats and prices.
How big is a 240 x 120 cm slab?
One slab covers 2.88 m2. That is the number used to size a job: divide the panel area by 2.88 m2 and round up.
What thickness is normal for 240 x 120 cm?
9 mm is the common specification. Thickness sets stiffness and weight, not surface durability, which is the same at every thickness.
How much does a 240 x 120 cm slab weigh?
About 62 kg. That weight decides how many people or what lifting aid is needed, and how strong the support frame must be.
Is 240 x 120 cm big enough for a kitchen island?
Yes, and this is the format that avoids a join across a worktop. An island longer than the slab still needs a join, but it falls at the end rather than in the middle.
How many slabs for a three metre worktop?
A 3 m worktop at 60 cm deep is 1.8 m2, so one slab is enough. What decides the count is the vein direction and the offcuts needed for a splashback.
What does this format cost?
Market range is Rp 1.800.000 to Rp 2.100.000 per slab. Per square metre breakdown is on the pricing page for this format.
