For a 50 cm round mirror, the 20-inch glass mirror is the closest match, since its listing gives a diameter of approximately 50 cm (19.68 by 19.68 inches). The HARRITPURE 24-inch black mirror is larger than that target at 4.0 sq ft, and the 12-inch self-adhesive acrylic tile is smaller, at 30 cm across and 1 sq ft. Check the listed size against your wall before ordering. We have not tested these products, and the listings do not state weight capacities for the adhesive options.

1. HARRITPURE 24 Inch Round Mirror Black Circle Bathroom Mirror — Largest listed footprint

Listed details: dimensions 24″ L × 24″ W; item weight 5.3 pounds; material Aluminum; color Black.

The HARRITPURE round mirror has a 24-inch by 24-inch footprint, making it larger than the requested 50 cm size. Its black aluminum alloy frame uses a brushed, frosted finish, while the listing states that the 5 mm high-definition float glass provides a clear reflection without color changes. The listing also describes the frame as resistant to oxidation and corrosion and suitable for bathroom use. Installation accessories are included, and the listing says installation requires one hole in the wall. At 5.3 pounds, it is the heaviest listed option, with a 4.0 sq. ft. footprint.

Pros

  • The 5 mm glass is described as high-definition and resistant to image color changes.
  • Aluminum frame is listed as resistant to oxidation and corrosion.
  • Installation accessories are included, with one wall hole required according to the listing.

Cons

  • Its 24-inch footprint is larger than a 50 cm target, so verify the available wall space.
  • The listing does not state the mirror’s interior reflective diameter.
  • At 5.3 pounds, it may require more secure mounting than the lighter options.

Who it is for / who should skip it: Pick it if you want a black framed bathroom mirror and have room for the larger 24-inch size. Skip it if matching approximately 50 cm is more important than the aluminum frame.

2. 20” Glass Round Mirror for Wall Decor, 2mm Circle Bathroom Mirror — Middle listed footprint

Listed details: dimensions 19.68″ L × 19.68″ W; material Glass; color Mirror.

This frameless round glass mirror is the closest match to the keyword: the listing identifies its diameter as approximately 19.68 inches, or 50 cm. It has a 19.68-inch by 19.68-inch footprint and a 2.69 sq. ft. area, placing it between the other two listings. The contemporary design uses glass for both the mirror and frame listing fields. The listing states that its smooth, flat HD glass provides clear reflection without distortion. Double-sided adhesive tapes are included for installation, and the instructions advise cleaning the wall first. The listing does not state the mirror’s weight or mounting capacity.

Pros

  • The listing specifically identifies the diameter as approximately 50 cm.
  • Frameless styling suits contemporary wall and bathroom decor.
  • Double-sided adhesive tapes are included for installation.

Cons

  • The listing specifies 2 mm thickness, which is less than the 5 mm glass listed for product 1.
  • The listing does not state the mirror’s weight or how much mounting load the adhesive supports.
  • Adhesive installation requires a clean wall and may not suit every wall surface.

Who it is for / who should skip it: Pick it if you want the closest listed match to a 50 cm round mirror with a frameless contemporary look. Skip it if you need a stated weight, a framed design, or mounting hardware beyond adhesive tape.

3. 12” Round Wall Mirror Tiles Self Adhesive Circle Mirror for Wall — Smallest listed footprint

Listed details: dimensions 12″ L × 12″ W; item weight 8.16 ounces; material Acrylic; frame Glass; color Clear.

The 12-inch round wall mirror is the smallest option and does not match the requested 50 cm size. The listing describes it as a flexible, shatter-proof acrylic mirror with a 2.5 mm thickness and a clear reflective coating. Its listed diameter is 30 cm, and its 12-inch by 12-inch footprint covers 1.0 sq. ft. The self-adhesive design is intended for a flat wall, with the listing noting that flatter surfaces support better clarity. At 8.16 ounces, it is much lighter than the framed glass option. The listing does not state adhesive durability or a weight capacity.

Pros

  • Acrylic is described as flexible, shatter-proof, and safer than glass.
  • The 8.16-ounce listed weight makes it the lightest option.
  • Self-adhesive installation avoids the wall hole specified for product 1.

Cons

  • Its listed 30 cm diameter is substantially smaller than the requested 50 cm.
  • The listing says it should be applied to a flat wall for the best result.
  • The listing does not state adhesive durability or weight capacity.

Who it is for / who should skip it: Pick it for a small decorative accent or lightweight mirror where shatter resistance matters. Skip it if you need a functional 50 cm mirror or a larger reflection area.

What to check before buying round mirror 50 cm

Start with diameter: for a round mirror 50 cm, choose a listing that explicitly states approximately 50 cm rather than relying only on a rounded product title. Product 2 is the clearest match because its listing gives an approximately 50 cm diameter. Product 1 lists a 24-inch by 24-inch footprint, and product 3 lists a 12-inch footprint and a 30 cm diameter, so neither should be treated as an exact 50 cm choice.

Next, measure the available wall area. Product 1 covers 4.0 sq. ft., product 2 covers 2.69 sq. ft., and product 3 covers 1.0 sq. ft. If the mirror must fit a tight space, product 3 has the smallest listed footprint; if you want the largest reflection area, product 1 is largest. Do not rank these sizes as interchangeable with a 50 cm diameter: the listings use different measurements and product 1 is larger than the target.

Choose the surface and frame style deliberately. Product 1 combines a black aluminum frame with 5 mm glass and is described as suitable for bathroom environments. Product 2 is a frameless glass design with 2 mm thickness. Product 3 uses 2.5 mm acrylic and is described as flexible and shatter-proof, making it a different choice from glass rather than a direct size substitute.

Finally, match installation to the wall. Product 1 includes accessories and calls for one wall hole. Product 2 uses included double-sided adhesive tape and requires a clean wall. Product 3 is self-adhesive and is advised for a flat wall. The listings do not state product 2’s weight, product 3’s adhesive durability, or either adhesive option’s weight capacity, so verify those details before mounting.

Worked example: fit math for these three options

This worked example is our own planning arithmetic from the listed dimensions, not test results. The wall length and walkway width are assumed example values; replace them with your measurements.

Wall example. Assume 36 inches of clear wall.

  • HARRITPURE 24 Inch Round Mirror Black: 36 − 24 = 12 inches spare; centred, 6 inches on each side before trim, plugs or curtains.
  • 20” Glass Round Mirror for Wall: 36 − 19.68 = 16.32 inches spare; centred, 8.16 inches on each side before trim, plugs or curtains.
  • 12” Round Wall Mirror Tiles Self: 36 − 12 = 24 inches spare; centred, 12 inches on each side before trim, plugs or curtains.

Walkway example. The US Access Board gives 36 inches as the minimum clear width for an accessible route. That figure is a yardstick, not a rule for private homes. To keep 36 inches clear beside each product, the walkway between it and the opposite obstacle must be at least 36 inches plus its depth:

  • HARRITPURE 24 Inch Round Mirror Black: 36 + 24 = 60 inches of total path width.
  • 20” Glass Round Mirror for Wall: 36 + 19.68 = 55.68 inches of total path width.
  • 12” Round Wall Mirror Tiles Self: 36 + 12 = 48 inches of total path width.

Footprint. Depth × width, converted at 144 square inches per square foot:

  • HARRITPURE 24 Inch Round Mirror Black: 24 × 24 = 576 sq in, or 4 sq ft.
  • 20” Glass Round Mirror for Wall: 19.68 × 19.68 = 387.3 sq in, or 2.69 sq ft.
  • 12” Round Wall Mirror Tiles Self: 12 × 12 = 144 sq in, or 1 sq ft.

Mistakes to avoid

  • Confusing inches with centimeters. A 50 cm mirror is not the same as a 50-inch mirror, and the listings use both centimeter and inch descriptions. Product 2 is the only one that explicitly states approximately 50 cm.
  • Ignoring the actual footprint. Product 1 lists a 4.0 sq. ft. footprint, product 2 lists 2.69 sq. ft., and product 3 lists 1.0 sq. ft. Measure the wall before choosing based on the listing title.
  • Treating acrylic like glass. Product 3 is acrylic, while products 1 and 2 are described with glass mirror surfaces. Choose acrylic for the listed shatter-proof flexibility, not because it has the same optical or mounting characteristics as glass.
  • Assuming adhesive works on every wall. Product 2 advises cleaning the wall, and product 3 is advised for a flat wall. The listings do not state adhesive weight capacities or durability, so verify compatibility before installation.

Frequently asked questions

Which listed mirror is closest to 50 cm?

Product 2 is the closest and clearest match. Its listing identifies the diameter as approximately 50 cm and gives a 19.68-inch by 19.68-inch footprint. Product 1 is listed at 24 inches, while product 3 is listed at 30 cm, so those are not equivalent 50 cm options.

Is product 1 exactly 50 cm wide?

No. Product 1 is listed as 24 inches by 24 inches, not 50 cm. Its footprint is 4.0 sq. ft., the largest of the three. Because its listed size is larger than the requested target, measure your wall and verify the dimensions before ordering.

Which mirror is best for a small wall?

Product 3 has the smallest listed footprint at 1.0 sq. ft. and weighs 8.16 ounces, but its listed diameter is only 30 cm. Product 2 covers 2.69 sq. ft. and matches approximately 50 cm. Choose based on whether minimum size or the requested diameter matters more.

Do these mirrors include mounting hardware?

Product 1 states that installation accessories are included and requires one wall hole. Product 2 includes double-sided adhesive tapes. Product 3 is described as self-adhesive. The listings do not state weight capacities for the adhesive options, so verify wall compatibility and support before installation.
