Work out the area, choose the panel orientation and count whole mats. Use our hire and sales coverage tables, worked layouts and a real 200m roadway to plan your starting quantity.
To estimate ground protection mat quantities, divide the area to cover by the appropriate area per mat and round up. To plan a route or rectangle, count whole panels across the width and whole rows along the length, then multiply them. Add the actual panels needed for turns, passing places, entrances and other working areas.
This does not resolve the shape, edges, joints or orientation. Gross mat area is only a preliminary proxy where a verified installed area is unavailable.
Use confirmed connected dimensions for the final layout. Then count separately drawn bays, turns, transitions and agreed spares.
A correct count does not select a suitable mat. Product choice also depends on ground support, loads, traffic, turning and duration. Our CBR guide and load guidance explain those checks.
Use the figures for the exact mat you will receive. Nominal area is calculated from outside panel dimensions; usable area describes the connected coverage where published. Neither figure replaces a whole-panel layout.

| Mat | Panel size | Area per mat | Quantity planning point |
|---|---|---|---|
| TM10Recycled rubber | 1.20 × 0.80m | 0.96m²Nominal / gross | Plan slot-fit panels, clear walkway width and ramped transitions together. |
| TM50Current hire · ISOtrack L | 2.41 × 1.20m | ≈ 2.89m²Nominal / gross | Check both orientations and confirm the connected width and panel advance. |
| TM120Heavy-duty HDPE | 3.00 × 2.50m | 7.50m²Nominal / gross | Orientation changes the row count. Include the strap-and-bolt connection layout. |
| TM200MegaDeck HD+ · flagship | Approx. 4.3 × 2.3m overall | 7.85m²Published usable coverage | Use the overlapping module, approximately 3.96 × 1.98m, and the agreed MDX layout. |
Hire references: TM10 specification, TM50 specification, TM120 specification and TM200 specification. Approximately 2.89m² is the rounded result of 2.41 × 1.20m.
MegaDeck HD+ has 9.75m² published gross area and 7.85m² usable area in a connected layout. Its flanges overlap and are secured with MDX connections.
Use the published usable coverage for an area estimate and the usable module for the layout. Do not multiply the rounded outside dimensions or deduct a second generic overlap percentage.
The metric lengths are rounded supplier figures. Approximately 3.96m across is not 4m of clear working width.

Sales references: TM10 PDF, TM40 PDF and TM50 PDF. TM40 nominal area is 2.9889m², shown rounded to 2.99m². TM50 nominal area is 2.892m², shown rounded to 2.89m².
Buying used mats? The used sales range includes TM10 and full-size TM50 EuroTrak at 2.40 × 1.20m, 2.88m² nominal area. This is a different product version from the current TM50 hire panel above. Confirm the actual batch dimensions, condition, availability and connector fit before calculating the order.
Choosing the commercial route? Read ground protection mats: hire or buy. These coverage tables compare dimensions, not load capacity or product suitability.
These are arithmetic examples for simple rectangles. They do not approve the product or route width for particular traffic. Nominal dimensions illustrate the method; final quantities use the agreed connected layout.
TM10 · 1.20 × 0.80m nominal panel
Allows for the rectangle only. Confirm the installed slot-fit geometry, required clear walkway width and ramped edges. Corners, entrance areas and spares are additional.
TM50 hire · 2.41 × 1.20m nominal panel
A quantity example, not a recommended vehicle-route width. Check the actual connected width, vehicle clearance, mirrors, swept path and traffic controls. Do not use the nominal 10mm excess as an operating allowance.
TM120 · 3.00 × 2.50m nominal panel
Orientation matters: turning the panels gives 7 across × 6 rows = 42 panels, before connection allowances. Reconcile joints, boundaries, gates and any separate working zones on the final layout.
TM200 MegaDeck HD+ · usable module
This uses the supplier’s approximate usable module, not the outside flange dimensions. A 3.96m module does not provide a 4m clear route. Confirm clear width, edges and the complete MDX layout before ordering.
Final count = agreed base layout + separately counted features + agreed spares. The examples exclude passing places, turns, ramps, perimeter details and contingency. The diagrams show representative rows, not complete installation plans.
For a UK outdoor event, TrackMatz installed a 200m × 2.4m route using 167 TM50 mats and 334 joiners. Installation was completed on 20 August 2026, followed by uplift on 2 September. All mats and joiners were returned and counted.
The planning lesson: record the mat quantity, connected width and components together. The supplied and recovered counts make this a useful project reference.
These are recorded quantities for that project, not a universal joiner ratio or an approval for another site. Use the specification of the actual TM50 version supplied when planning a new job.
Read the full installation and uplift case study →Draw the areas that vehicles and people will actually use. Split irregular shapes into rectangles, then reconcile their joins on one layout to avoid counting the same area twice.
Measure the additional bay and count its whole panels. Do not count the area already included in the through route twice.
Agree the working width and traffic arrangements for both lanes. The correct layout is not necessarily twice the single-lane quantity.
Use the agreed vehicle swept path to measure the widened corner. Long vehicles can cut inside the path followed by the cab.
Count gate approaches, crossings, laydown areas and any widening separately. Ramped edges are separate components, not extra full mats. Confirm how the mat layout meets roads, footpaths and other surfaces.
Count the correct two-way or four-way joiners, TM120 straps and bolts, or MegaDeck MDX components from the actual junctions and installation method. Agree a spare quantity with a reason, rather than applying a blanket percentage.
Before confirming the system: review ground support and CBR evidence where relevant, axle or track loads, traffic frequency, turning, weather and hire duration. Ground weakness is not solved by adding an arbitrary number of mats. Cranes, outriggers, voids, concentrated loads and other high-consequence uses may require a competent engineering assessment. See load guidance and delivery and installation.
Measure the required length and width. For an area-only first estimate, divide square metres by the appropriate area per mat and round up. For a buildable rectangle or route, divide the width by the laid panel width and the length by its advance; round each up, then multiply. Add the separately planned turns, passing bays, transitions and contingency.
The answer depends on the mat and the shape. As an area-only example, 100 ÷ 7.50 gives 13.33, rounded up to 14 TM120 panels. For a 10m × 10m square, laying 2.5m across and 3m along gives 4 panels across × 4 rows: 16 panels on that nominal layout. The area-only estimate does not allow for whole-panel edges or connections.
The nominal areas are 0.96m² for TM10, approximately 2.89m² for the current TM50 hire panel and 7.50m² for TM120. TM200 MegaDeck HD+ has 7.85m² published usable coverage in a connected layout. In the new sales range, TM40 is approximately 2.99m² and TM50 approximately 2.89m². Gross or nominal area must be reconciled with the actual connection and layout.
There is no universal percentage. Use the selected product’s connected geometry, count the actual extra layout features, then agree a specific number of spare mats. MegaDeck’s published usable area already accounts for its overlapping layout; do not apply a second generic overlap deduction to it.
Agree the working width from the traffic and site plan, including mirrors, vehicle swept path, edge clearance, passing arrangements and traffic controls. A panel width is not automatically a suitable road width. For example, a MegaDeck usable module of approximately 3.96m must not be described as a 4m clear route.
Count them from the selected mat system and its connection plan. Two-way and four-way joiners, TM120 straps and bolts, TM10 ramped edges and MegaDeck MDX connections have different uses. Confirm junctions, perimeter transitions, compatible components and spares. A joiner-to-mat ratio from one project is not a universal rule.
Only when the exact product version matches. The current TM50 hire panel is listed as 2.41 × 1.20m, approximately 2.89m² nominal area. The used TM50 EuroTrak full-size panel listed for sale is 2.40 × 1.20m, 2.88m². Confirm the supplied batch, dimensions, condition and connector compatibility.
Not automatically. The footprint sets the area, but the ground, loads, traffic and duration may change the suitable mat, preparation or designed layout. A different mat size can then change the count. CBR helps assess the ground; it is not a quantity multiplier or a universal vehicle-weight limit.
