Key Decision

Funtek’s current general slab range covers five nominal formats: 900 × 1800, 900 × 2600, 1200 × 2400, 1200 × 2600 and 1600 × 3200 mm. Choose the smallest format whose confirmed usable area can hold the required cut pieces, then verify thickness, pattern direction, workshop capacity, delivery access and the installation system.

Published dimensions are a starting envelope, not a promise that every millimetre is available for finished work. Exact size, thickness and usable cutting dimensions must be confirmed for the selected design and order.

Funtek Sintered Stone Slab Sizes at a Glance

The table uses the current formats shown across Funtek’s full slab library. Nominal area is simply length × width; it helps compare formats, but it does not include perimeter trimming, kerf, defect avoidance, pattern positioning or offcuts.

Nominal format Nominal area Useful planning role Current thickness note
900 × 1800 mm 1.62 m² Compact furniture parts, smaller wall fields and modules where handling space is limited 6, 9, 12 and 15 mm are listed in the current general slab library
900 × 2600 mm 2.34 m² Tall narrow wall panels, cabinet or furniture components and linear cut programs 6, 9, 12 and 15 mm are listed in the current general slab library
1200 × 2400 mm 2.88 m² Large wall modules, floor layouts and repeatable project panels 6, 9, 12 and 15 mm are listed in the current general slab library
1200 × 2600 mm 3.12 m² Extended wall or furniture pieces and selected countertop runs 6, 9, 12 and 15 mm are listed in the current general slab library
1600 × 3200 mm 5.12 m² Large islands, long worktops, reception counters and low-joint architectural layouts 6, 9, 12 and 15 mm are general options; selected 20 mm supply is confirmed by quotation

This is a format taxonomy, not an availability promise for every colour, finish and thickness combination. Ask Funtek to confirm the exact combination against the selected slab before drawings or quantities are released.

What Does “Standard Slab Size” Mean?

There is no single universal sintered stone footprint. “Standard” normally means a repeatable production format offered by a particular supplier or collection. Another manufacturer may use different press dimensions or market labels such as standard, large, jumbo or super-jumbo.

For procurement, the useful question is not “What is the industry standard?” but “Which current Funtek format can contain my required pieces in the approved orientation?” That keeps the comparison tied to a real supply range rather than a generic size found elsewhere.

A format name is descriptive; the dimension in millimetres and the confirmed usable cutting area are the purchasing specification.

Nominal Size, Usable Size and Finished Size Are Different

Three rectangles matter in a slab order. Confusing them is one of the fastest ways to approve a piece that does not actually fit.

1. Nominal slab

The catalogue or quotation format, such as 1600 × 3200 mm. It defines the supplied slab envelope.

2. Usable cutting area

The confirmed area available after the actual slab perimeter, inspection and production conditions are considered.

3. Production blank

The rectangle the fabricator needs before final machining. It may be larger than the finished part because of edge and cutting requirements.

The production blank must fit inside the usable area—not merely inside the nominal rectangle. Required allowances are product- and fabricator-specific, so a generic trimming percentage should not be inserted into a purchase order.

Pattern can reduce practical freedom even when the geometry fits. A directional vein may prevent a 90-degree rotation; bookmatch faces may have fixed relationships; and a visible focal area may need to avoid a particular part of the print. Approve the slab image or layout together with the dimensions when pattern placement matters.

Slab Size and Thickness Solve Different Problems

Length and width determine whether pieces can be nested and where seams may fall. Thickness changes weight, edge appearance, fabrication behaviour, support and fixing requirements. A larger footprint does not compensate for the wrong thickness, and a thicker slab does not make an undersized format fit.

Funtek’s current general library lists 6, 9, 12 and 15 mm across its standard format presentation, with selected 20 mm project supply requiring confirmation. The correct combination depends on the exact product and assembly. For kitchen work surfaces, use the dedicated countertop thickness guide rather than treating this general size table as an engineering prescription.

Do not approve a slab from a size-only schedule: the same 1600 × 3200 mm footprint can create very different weight, support, edge and handling conditions at different thicknesses.

Which Slab Size Fits Each Application?

Application labels do not create fixed size rules. The table below shows what normally controls the format decision and where the next detailed review belongs.

Application Main size control How to use the Funtek range Next check
Countertops and islands Largest one-piece blank, seam position, cutouts and vein direction 1200 × 2600 or 1600 × 3200 mm may suit longer pieces; the drawing decides Kitchen-specific slab-size planning and countertop project supply
Furniture and table tops Repeated component sizes, edge design, support, handling and yield 900 × 1800 and 900 × 2600 mm can reduce unused area for compact parts; larger formats may combine more pieces Furniture and tabletop programs
Interior walls Floor-to-ceiling height, joint grid, openings, substrate and lifting route 900 × 2600 and 1200 × 2600 mm support tall modules; 1200 × 2400 mm suits common large wall fields Final panelization and installation-system review
Facades Engineered panel module, fixing system, wind and structural design, access and replacement strategy Start from the elevation grid rather than selecting the largest slab by default Facade panel and system scope
Floors Room grid, movement joints, finish, substrate, equipment and installation sequence 1200 × 2400 mm can reduce joints, while smaller cut modules may improve site handling and replacement Project-specific flooring and installation specification

Countertops and Islands

General format selection begins with the longest and widest pieces that must remain seamless. Kitchen geometry, waterfalls, appliances and seam preferences then create a more specific task. A099 remains the owner of choosing a slab size for kitchen countertops and islands; this article does not repeat its worked kitchen comparison.

Furniture

Furniture programs often benefit from repeatable nesting rather than maximum slab area. A 900 mm-wide format may align efficiently with table, vanity, shelf or panel dimensions, while a 1600 mm-wide slab may hold multiple parts side by side. The right answer depends on the cut list, orientation and whether remnants can be reused in the same production run.

Walls, Facades and Floors

For architectural surfaces, the joint grid and installation system can matter more than the raw slab footprint. Full-height panels may reduce horizontal joints, but they also enlarge the lifted component. Facades add engineered fixing and replacement requirements; floors add movement-joint, substrate and installation-sequence constraints. The finished panel module should be approved before raw slab size is locked.

Transport and Site Access Can Rule Out the Largest Format

A slab that fits the drawing can still fail the delivery route. Check the full chain: factory cutting table, lifting equipment, A-frame or crate, container and truck, unloading equipment, doors, corridors, elevators, stairs, turning space and the final installation position.

The check must cover both raw slabs and finished pieces. A fabricated island or wall panel may have a different orientation, protection frame or turning envelope from the original slab. If a one-piece component cannot reach the site, the drawing needs a planned seam or a different installation route before production.

Use the sintered stone weight calculator to estimate net slab weight from format, thickness and quantity. For packing and freight scope, continue to Funtek’s global slab-shipping page. Site access and local lifting remain project-specific approvals.

Cut Yield: A Bigger Slab Does Not Always Waste Less

Nominal slab area is not finished yield. Yield comes from fitting fixed rectangles within the usable area while respecting kerf, edge allowances, pattern direction, defects, cutouts and remnant value. Two layouts with the same finished square metres can require different slab counts.

A 1600 × 3200 mm slab has 5.12 m² of nominal area, but dividing required area by 5.12 only creates an area estimate. It does not prove that the pieces nest. A long narrow set of furniture components may yield better from 900 × 2600 mm panels, while a large island may require 1600 × 3200 mm because no smaller format contains its one-piece blank.

Use the area calculator for an early material estimate, then use the dedicated slab-quantity and nesting guide when whole-slab count is the decision. Final quantity should come from an approved cutting layout.

How to Choose a Sintered Stone Slab Size

Seven inputs before release

  1. List every finished piece with length, width, units and drawing revision.
  2. Mark one-piece requirements and acceptable seams instead of assuming every component must be seamless.
  3. Fix orientation rules for veins, bookmatch faces, surface direction and visible focal areas.
  4. Compare current formats and choose the smallest candidate that can contain the required production blanks.
  5. Confirm usable size and thickness for the selected design, finish and order.
  6. Test fabrication, packing and site access for both raw slabs and finished components.
  7. Approve the cutting layout and whole-slab quantity before purchase or production release.

At that point, “900 × 1800 versus 1600 × 3200” is no longer a general preference. It is a documented choice connected to a drawing, a supply combination and a route to the installed position.

The Bottom Line

Funtek’s current general slab formats run from 900 × 1800 to 1600 × 3200 mm. The largest format offers the biggest nominal envelope, but the best format is the smallest confirmed usable slab that completes the approved cut layout without creating avoidable access, handling or yield problems.

Keep the responsibilities separate: this page owns general slab-format taxonomy; the kitchen size article owns kitchen-specific one-piece selection; the quantity article owns whole-slab nesting; and the thickness guide owns countertop thickness. Together, they move a project from a rough dimension to a quote-ready slab schedule.

Sintered Stone Slab Size Questions

01

Are all five Funtek slab formats available in every design and finish?

No. The five formats define Funtek’s current general range, but the available size, thickness and finish combination must be confirmed for the selected design and order.

02

Can Funtek confirm usable slab dimensions before cutting?

Yes. Select the design and thickness first, then send the production blanks or drawings so the usable cutting area and layout can be reviewed for that order.

03

Does a sink or cooktop cutout reduce the number of slabs required?

Not by itself. The full countertop blank must still be cut before the opening is removed. Whole-slab quantity depends on the complete nesting layout, not the net area left after cutouts.

04

Is 20 mm available in every Funtek slab size?

No. Selected 20 mm project supply is confirmed separately. Do not apply 20 mm availability to every format or design without a current quotation.

05

Should access be checked for the raw slab or the finished piece?

Check both. The raw slab must pass through fabrication and packing, while the finished countertop or panel may have a different orientation, protection frame and turning envelope on site.
