400x400 mm Tiles (16x16 inch): Uses, Coverage and Tips

400x400 mm is a square size you mostly meet outdoors. In Bengaluru it is very common for house parking areas, driveways and sit-outs, where thick, textured tiles in this size handle vehicles, rain and dust better than smooth indoor tiles.

Size in feet and where it is used

400 x 400 mm is about 1.3 x 1.3 ft, close to 16 x 16 inches. It is typically used on:

• Parking areas and car porches of independent houses
• Driveways and entrance paths
• Garden paths and sit-outs
• Some older indoor floors, though indoors it has largely given way to 600x600

Coverage per tile

The working: 400 x 400 = 160,000 sq mm, divided by 92,903 sq mm per sq ft, gives 1.72 sq ft. Add 5 to 10 percent for cuts along gates, drains and curved edges. Use the tile calculator for your exact area.

Box quantities change with manufacturer and thickness, so check the label or ask us instead of assuming.

Tile types you usually find in this size

• Parking tiles, which are usually thicker than indoor floor tiles, with textured or patterned surfaces
• Heavy-duty anti-skid outdoor tiles
• Interlocking-look, cobble-look and stone-look designs
• Some full body vitrified tiles, where scratches show less because the colour runs through

Laying and handling tips

• For parking, the base matters as much as the tile. A solid, well-compacted concrete base stops tiles from cracking under car wheels.
• Give the area a slight slope so rainwater drains away and does not pool, which matters in the monsoon.
• Use a strong outdoor-grade adhesive or a proper mortar bed, and fill joints fully so water cannot get under the tiles.
• Thick parking tiles are heavy. Carry and stack boxes carefully to avoid chipped edges.
