Our Top Picks
The best monitor dust cover is the one cut to your screen’s real width and height with room left for the stand, because a cover that is too tight or too short stops being protection and starts being a nuisance. A dust cover is fabric or vinyl, so the decision is mostly tape-measure work plus a check on material claims. Seven listings are covered here, from a pair of SZBRO covers to elastic, ultrawide and novelty options. The sizing arithmetic below turns a diagonal into an estimated minimum cover size, so you can rule listings in or out before reading a single review.

What to check before you pick a size
Do the sizing arithmetic first
A monitor’s diagonal is not a cover size. For a 16:9 screen, width is roughly 0.87 times the diagonal and height roughly 0.49 times; for a 21:9 ultrawide, roughly 0.92 and 0.39. The cover must also reach down over the stand, which we estimate adds about 5 inches of height (stands vary, so measure yours). The numbers below are estimates for sizing only.
| Diagonal | Panel width x height (in, estimate) | Minimum cover (in, estimate) |
|---|---|---|
| 24 in, 16:9 | 20.9 x 11.8 | 22 x 17 |
| 27 in, 16:9 | 23.5 x 13.2 | 25 x 18 |
| 32 in, 16:9 | 27.9 x 15.7 | 29 x 21 |
| 34 in, 21:9 | 31 x 13 | 32 x 18 |
Applying it to the listings: the SZBRO 25W x 17H cover suits a 24-inch screen comfortably but is borderline for a 27-inch with a tall stand. The SZBRO 23W x 16H vinyl is tighter still. That listing also mentions an all-in-one 24-inch machine, and an all-in-one with its stand is usually taller than a bare monitor, so check how the seller defines the dimensions and compare them with your own screen’s measured height before you buy.
Read the material claims carefully
Words like antistatic, waterproof and anti-tear are seller wording, and the titles give no thickness or fabric weight. Elastic fabric forgives a small measuring error; fixed vinyl does not. Fabric can also trap grit, which is why a screen should be wiped and dry before a cover goes on.
Power, heat and ventilation
Cover a screen only after it is switched off and has cooled; never cover a monitor that is running or in standby with vents blocked. Waterproof vinyl on a damp or warm panel can hold moisture against the glass.
Arms, stands and second screens
Arm-mounted screens sit higher and swing, so a cover with an adjustable bottom is easier to use; our monitor arms guide explains the height and reach involved. On a desk with a riser, add its height to the 5-inch stand allowance; the monitor stands roundup lists typical risers. With two screens you need two covers, and the dual monitor arms guide covers the spacing, which affects how easily covers slip on.
Do you need one at all?
If the desk is dusty, pets shed, or the screen sits unused for days, a cover saves wiping. A monitor used daily in a clean room gains little.
The seven covers, listing by listing
SZBRO Heavy Duty Anti-Tear Monitor Dust Cover (25W x 17H)
The title promises a heavy-duty, anti-tear full-body protective case for LED and LCD screens, with an adjustable tight rope at the bottom and a stated 25 inches wide by 17 inches high. The rope is the useful feature: it lets you cinch the hem under the stand so the cover does not ride up. ‘Universal’ sits awkwardly beside a single fixed size, so match your own measurements to the numbers. Thickness and fabric are not given, so heavy duty is the seller’s description. If you stack it on a desk riser, add that height to the stated 17 inches before deciding.
Pros
- Dimensions are stated in the title
- Adjustable bottom rope helps hold the cover down
- Mid-range tier
Cons
- ‘Universal’ conflicts with one fixed size
- Material and thickness not stated
Who it’s for: owners of 24-inch-class monitors on standard stands.
SZBRO Antistatic Vinyl Monitor Cover (23W x 16H)
A cheaper vinyl option, described as antistatic, waterproof and sized 23 inches wide by 16 inches high, with a nod to the 24-inch iMac. Vinyl wipes clean, which suits a desk with spills nearby, though a waterproof cover is not a reason to leave it on a running screen. The 16-inch height is the number to question for any model that is taller than a plain monitor, as explained in the sizing notes above. Vinyl can also crease in storage, so expect a few folds the first time you fit it.
Pros
- Budget tier
- Wipe-clean material per the title
Cons
- Smallest stated size in the set; tight for taller screens or thick stands
- Antistatic and waterproof are seller claims
Who it’s for: someone with a compact monitor who wants an inexpensive sleeve.
DEEP DEER Universal Elastic Monitor Dust Cover
This elastic fabric cover is listed as waterproof, dustproof and water-resistant, with pet hair protection and an elastic cord. The size list reads 19, 21, 22, 23 and 27 inch, and 24 inch is missing, which could be a typo or a real gap; since 24 inch is the most common size, confirm it before ordering. The all-black look is neutral. Elastic makes fit more forgiving than the fixed-dimension covers, though loose fabric can sag on small screens. Check the elastic cord at the bottom is long enough to reach under your stand base.
Pros
- Elastic fit tolerates small sizing errors
- Pet hair protection is named
- Mid-range tier
Cons
- 24-inch is absent from the size list; confirm
- Waterproof and dustproof are seller claims
Who it’s for: households with pets and screens in the 19 to 27 inch range.
kwmobile Monitor Cover for 31-32 Inch Screens
The title gives the size range, 31 to 32 inch, the brand and the color, and nothing about material, closure or dimensions in inches. By our arithmetic a 32-inch 16:9 panel is about 28 inches wide, so a cover for the class is a relatively large piece of fabric. The listing sits at the top price tier in this set. That means you are paying for a labeled fit rather than extra features, so read the product page for the fabric. A labeled size spares you the arithmetic, but you should still compare it with your own width and stand height.
Pros
- Explicit 31 to 32 inch fit
- Black finish blends with most desks
Cons
- Top price tier for the least detail
- Material and closure not stated in the title
Who it’s for: owners of 32-inch monitors who want a size-specific cover.
MVCTOYH Dust Cover for All-in-One 27-32 Inch
The shortest title in the set: a monitor dust cover for all-in-one computers, 27 to 32 inch. All-in-one PCs are thicker than plain monitors because the electronics sit behind the screen, so confirm the cover allows for that depth. A range of five inches also covers panel widths of about 23.5 to 28 inches by our arithmetic, a spread an inelastic cover would struggle with, so find out whether this one stretches. The title says nothing about a rear opening for cables, which matters when a power lead exits behind the base.
Pros
- Low price tier
- Explicit all-in-one use, which helps with the thicker body
Cons
- Material, closure and dimensions not given
- Wide size range; fit may vary at the ends
Who it’s for: all-in-one PC owners who will read the product page for dimensions.
Monfurise Cat Ear Monitor Cover
The novelty entry in this group. It is a pink, soft elastic cover with cat ears, listed for 20 to 29 inch displays and pitched at gaming and home office desks, so the buyer is clearly someone who wants personality. It does the dust job like any elastic cover, but the ears add height and make it a decor decision as much as a protective one. Skip it for a shared or professional space unless you like the look. As with any elastic cover, wipe the panel first so the fabric does not drag grit across it.
Pros
- Lowest price tier
- Elastic fit across 20 to 29 inch, a wide window for the price
Cons
- Decor-first design; not for every desk
- Ears add height; check shelf clearance
Who it’s for: someone who wants a playful desk and a dust cover in one.
kwmobile Monitor Cover for 34-35 Inch Screens
The only cover here sized for ultrawide-class screens, 34 to 35 inch. By our arithmetic a 34-inch 21:9 panel is roughly 31 inches wide but only about 13 inches tall, so a cover for a normal widescreen would be the wrong shape. The ‘Don’t Touch My Screen’ print is a design choice, in white and black, and unlikely to suit a client-facing desk. Ultrawides also tend to have wider stands, so check that the hem reaches the base. Material is not described in the title, and the white and black colorway means a dark desk shows it more.
Pros
- Fits the ultrawide size class
- Mid-range tier
Cons
- Printed message divides opinion and may not suit a shared office
- Material not stated
Who it’s for: owners of 34-inch ultrawides who are comfortable with the print.
How we picked these
This list was built from titles, published specifications, manufacturer documentation and buyer reviews in general terms. Nobody on the team used or measured these units. Dust covers are simple products, so the main filter was whether each title states usable size information, followed by what it says about material and closure. Anything the title leaves open is marked “check the listing.” Price tiers are relative to this set of seven and move often. Where the listings overlap on size, we preferred the one whose title states more.
Common buying mistakes with dust covers
- Sizing by diagonal alone. A 27-inch screen and a 27-inch all-in-one have different bodies.
- Covering a running screen. Switch off, unplug if you can, let it cool, then cover.
- Ignoring the stand. A cover that ends at the panel leaves the stand and cables exposed. One that ends just above the desk rides up whenever you nudge the screen.
- Dragging fabric over grit. Dust the panel first, or the cover becomes sandpaper on glossy glass. A soft dry cloth does it.
- Treating waterproof as spill protection. It describes fabric, not safety with liquids near power.
- Overlooking ventilation. Tight vinyl on a hot monitor holds heat and moisture.
- Forgetting cables. A cover that pinches the power lead at the back can pull the base forward when you lift it off.
Verdict
From the titles alone, size labeling decides the pick. For common 24-inch-class screens the SZBRO heavy-duty cover states its dimensions and offers a bottom rope. DEEP DEER suits pet households if its size list includes your monitor. The kwmobile pair serve 32-inch and 34-inch screens, and the MVCTOYH is the budget route for all-in-ones, while the SZBRO vinyl is the cheap compact choice. The Monfurise is a decor purchase. Measure first, then confirm the size on the listing, since titles here rarely give fabric details.
Dust cover questions answered
Do monitors actually need dust covers?
No. A monitor works fine without one, and a microfiber cloth handles ordinary dust. A cover earns its place if the screen sits idle for days, if pets shed near the desk, or if you work in a dusty room. For a screen in daily use in a clean office, the benefit is small.
Can I cover a monitor that is still warm or on?
It is better not to. Switch the monitor off, unplug it or make sure standby is truly off, and let it cool before covering. Covering a running or warm screen blocks ventilation and can trap moisture, which waterproof vinyl makes worse. A few minutes after shutdown is usually enough for an ordinary monitor to cool.
How do I measure for a monitor dust cover?
Measure the screen’s width across the bezel, then the height from the desk surface to the top edge, including the stand. Add a little slack for the fabric, and write both numbers down before you open any listing. A tape measure is more reliable than the advertised diagonal, because stands and arms vary widely between models.
Are waterproof or antistatic covers better?
Both words are seller claims, and the titles do not describe fabric weight or certification standards. Antistatic may help dust cling less, and waterproof vinyl wipes clean, but neither is a safety feature. Judge covers on fit, material and ease of fitting, not on those labels alone, and always read what the seller says about material.
Will a cover fit a monitor on an arm?
It can, but fit is harder. Arm-mounted screens sit higher and swing, so a fixed cover that expects a stand may leave the arm bare or ride up. Look for an adjustable bottom or elastic cover, and measure from the top edge down to the arm clamp rather than to a stand base.
