Pros & Cons

Pros

  • ✓ 900x400mm desk-wide surface fits keyboard and full low-DPI arm swings
  • ✓ 3mm thin profile keeps desk height consistent under keyboard and mouse

  • ✗ Cloth surface picks up dust and needs periodic washing
  • ✗ Moderate friction is slower than glass or hard pads for high-DPI play
  • ✗ Rolls for transport, so it may need time to lie flat after shipping

Manufacturer description

The Logitech G840 XL is a 900x400mm cloth gaming mouse pad built for low-DPI players who need room for wide, sweeping arm swings and a full keyboard on the same surface. At 3mm (0.12 in) thick, it keeps a consistent height across your desktop, so you can angle your keyboard however you like without it catching the edge of your mousing area. Logitech tuned the cloth weave for moderate surface friction: enough resistance to stop a flick cleanly, little enough to keep low-speed tracking smooth. The texture is deliberately uniform, giving your mouse sensor consistent imaging for accurate cursor…

Frequently Asked Questions

How big is the Logitech G840, exactly?

It measures 900 x 400 x 3 mm (about 35.4 x 15.7 x 0.12 in) - wide enough to hold a full-size keyboard and still leave a large mousing zone. Measure your desk depth before ordering; 400mm is deep.

Is the G840 good for low-DPI gaming?

That is its design target. The cloth weave is tuned for moderate friction so rapid starts and stops land where you aim, and the 900mm width gives room for the wide arm swings low-DPI play requires.

Does it slide around during fast movements?

It has a no-slip rubber base specifically meant to prevent bunching and slipping during rapid, sweeping low-DPI movements. On a clean, flat desk it stays put.

Will it work with non-Logitech mice?

Yes. The surface texture is matched to Logitech G sensor calibration, but it is a standard cloth pad and works with any optical or laser mouse.
