It is a reasonable question. A plain black mouse pad looks like the safe choice. A desk mat covered in a detailed, brightly coloured picture looks as though it might confuse the sensor: bright next to dark, a hundred colours, fine lines. Will the cursor skip when it crosses from a pink patch to a black one?
The short answer is no. On a cloth desk mat, the printed image makes no practical difference to how a modern mouse tracks. Here is why, and what does matter.
How a mouse sees
An optical mouse has a tiny camera in its base. A light, usually an infrared or red LED, shines on the surface at a low angle. The camera takes pictures of a very small patch of that surface, thousands of times a second. A chip compares each picture with the one before and works out how far the patch has moved. That is your cursor movement.
The patch the sensor looks at is about a millimetre across, and it is seen under strong magnification. At that scale, the sensor isn't looking at your artwork. It is looking at the texture of the cloth: the weave of the threads, with its tiny peaks and shadows.
The printed picture is made of dye in those threads. To your eye, at arm's length, it forms a city or a nebula. To the sensor, at a fraction of a millimetre, it is cloth of one colour or another, and the weave is the same in every part.
Why colour doesn't matter much
- Most mice use infrared light. Dyes that look very different to you, hot pink, deep blue, bright green, often look much alike in infrared. The sensor may see far less contrast in the picture than you do.
- The sensor adjusts. It changes its exposure as it goes, as a camera does, to suit lighter or darker surfaces.
- It tracks texture, not picture. Even on a surface of one flat colour, the weave gives it plenty to follow.
This is why gaming companies sell cloth mouse pads covered in elaborate artwork, and why players use them in competition.
What does affect tracking
Some surfaces do cause trouble. They are not printed cloth.
- Glass and clear surfaces. There is no texture to see. Most mice fail on a glass desk.
- Mirrors and high gloss. The light reflects straight back and blinds the sensor.
- Very uniform, shiny surfaces, such as polished lacquer.
- Dirt. Dust, crumbs and hair on the mat or in the sensor opening cause skips and jitter. This is by far the commonest cause of bad tracking.
- A worn or uneven surface. Bumps, creases, and patches polished smooth by years of use.
- The mouse. An old or very cheap sensor is less tolerant than a current one.
A desk mat fixes the first three. If your desk is glass or glossy, a cloth mat is what makes the mouse work at all.
What changes the feel
Tracking accuracy is one thing. How the mouse feels in the hand is another, and that does vary between mats. It has nothing to do with the print.
- The weave. A smooth, fine weave lets the mouse glide fast. A coarser one gives more friction, which some people prefer for control and stopping.
- The thickness. A thicker, softer base is kinder to the wrist. The mouse sinks in very slightly under pressure.
- The base. A rubber base grips the desk so that the mat doesn't slide.
- The edges. A clean, flat edge doesn't catch your wrist.
- The mouse feet. Worn or dirty feet drag on any surface.
- Humidity. Cloth feels slower in damp weather.
Cloth mats sit in the middle of the range. They are slower and more controlled than hard plastic or glass pads, and they suit most people for both work and play.
For competitive players
If you play fast shooters at a high level, you may have firm preferences about glide speed and stopping power, and you may want a mat made for that purpose, with a particular weave and stitched edges. That is a question of feel and consistency. It isn't a question of whether a printed mat tracks. A printed cloth mat tracks.
Two terms you may see:
- DPI or CPI is how many counts the mouse reports per inch of movement. It is a property of the mouse and its settings, and the mat doesn't change it in any way you would notice.
- Lift-off distance is how high you can raise the mouse before it stops tracking. It varies a little between surfaces. Many mice have a calibration option in their software that tunes the sensor to the mat. If yours does, run it once on a new mat.
A quick test
If you want to be sure with your own mouse, try this when the mat arrives.
- Open a drawing program and choose a thin brush.
- Draw slow diagonal lines across the whole mat, passing over the lightest and darkest parts of the picture.
- Draw fast circles.
- Look at the lines. They should be smooth, with no jumps, steps or gaps.
If you see a skip, clean the sensor opening with a dry cotton bud and wipe the mat, and test again.
Our desk mats
Our mats have a printed fabric top and a non-slip rubber base, in three sizes: 14.4 × 12.1, 23.6 × 13.8 and 31.5 × 15.5 inches. The print is dyed into the fabric. It isn't a layer on top, so there is no raised edge between colours for the mouse to cross.
The designs run from quiet to very busy. Choose by what you want to look at. See the desk mat size guide, desk mat vs mouse pad and choosing a desk mat by colour scheme.
Keep it clean
A clean mat tracks better than a dirty one, whatever is printed on it.
- Wipe it weekly with a dry or slightly damp microfibre cloth.
- Deal with spills at once.
- Wash it gently by hand when it needs it, and let it dry flat and fully before use.
- Keep food away from it.
When the picture does matter
It matters to you. A very bright or busy mat directly under your hands can be distracting if you work at the desk all day. A dark or calm design is easier on the eyes. If your keyboard and mouse light up, a darker mat lets them show. That is a matter of taste and comfort, and it has nothing to do with the sensor. See desk mats for work and RGB lighting and neon art.
The short version
- A mouse sensor reads the texture of the cloth, at a scale far smaller than the picture.
- Printed colour and pattern don't affect tracking on a cloth mat with a modern mouse.
- Glass, gloss and dirt do.
- Weave and thickness change the feel.
- Choose the design you like.
