To frame an oval mirror, start with a frame made to match its actual curved outline and a mounting system designed to support the complete assembly. An oval is not a rectangle with rounded corners: four straight lengths cut at 45 degrees will not make a close-fitting oval frame.
A well-chosen border can give a plain reflection more presence above a console or vanity. Before starting, compare the cost of a suitable frame with a ready-framed mirror in the finish you want. The best-value option is the one that gives you a finished result without a difficult fit or improvised support.
Measure the curve, not only the width and height
Record the maximum width and height, glass thickness and the shape around the edge. Mirrors with the same overall dimensions can have different curves. A full-size paper template can help a frame maker check the fit, especially when the oval is elongated or slightly irregular.
Check how much overlap the frame is designed to have and whether it will cover any useful reflection. If your mirror is illuminated, do not cover its light band, controls, ventilation or mounting access. A decorative frame should not interfere with the functions you bought the mirror for.
Choose a framing route you can finish well
- A purpose-made oval frame: offers a defined rebate and a finished curved outline; confirm the glass dimensions it accepts.
- A custom frame maker: can work from the actual outline when the mirror is an unusual size or shape.
- A ready-framed replacement: is worth comparing when the existing mirror needs a new support system as well as a frame.
Finish paint or stain before fitting the glass where the frame design allows it. The frame maker’s method should specify how the mirror is retained and how the assembled piece hangs. Do not nail through the glass or assume ordinary wood glue will bond safely to mirror backing.
Check the mounting before adding weight
A new border adds weight and may change the hanging points. The original clips or adhesive were not necessarily designed for the altered assembly. Plan the complete support, check the wall and use the correct fixings. Our heavy mirror mounting guide explains the factors to consider.
If you like a suspended decorative look, read hanging a vintage mirror on a chain before choosing hardware. A decorative chain is not automatically suitable for the load.
Three finished alternatives to a framing project
50 × 70 cm black oval pivot mirror — £109. A slim black frame creates a crisp border, while the side pivots let you adjust the viewing angle. Allow 57 cm overall width including the brackets. This is a non-illuminated option for use with your room lighting.
54.5 × 85.5 cm black asymmetrical mirror — £79. If you want the softness of an oval with a less formal shape, the slim black outline makes a distinctive focal point. Its 2 cm profile and non-illuminated design keep the look simple.
50 × 70 cm oval dual-light mirror — £148. Front lighting and backlighting create their own border effect without adding a separate decorative frame. Dimming, three light colours and anti-fog support daily bathroom use.

Make the frame part of the room
Repeat a black border in a small accessory or tap finish for a coordinated look, or let the mirror be the contrast against pale tiles and timber. Keep enough wall visible around a bold frame so its shape can be appreciated.
