How the edge is treated affects both safety and style:
Standard mirrors typically come in thicknesses ranging from 1/8 inch (3mm) to 1/4 inch (6mm). Thinner glass is lightweight and suitable for small crafts or frame inserts, while 1/4-inch glass is the industry standard for large wall mirrors because it is more durable and less prone to "funhouse" distortion.
The sharp edges are sanded down. This is the most affordable option and is used when the edges will be hidden by a frame. buy mirror cut to size
The perimeter is cut at an angle (usually 1/2 inch to 1 inch wide), creating a decorative, sloping border that acts as a built-in frame.
The most critical step is getting the dimensions right. It is often recommended to measure twice and subtract about 1/8th of an inch (3mm) from the total width and height if the mirror is being fitted into a recessed frame or tight alcove. This "tolerance" ensures the glass doesn't crack during installation due to wall irregularities. How the edge is treated affects both safety
By focusing on precise measurements and the right edge profile, a custom-cut mirror becomes a long-lasting investment that enhances the light and perceived space of any interior.
The edges are buffed to a smooth, shiny finish. This is ideal for "frameless" looks. This is the most affordable option and is
The primary advantage is versatility. You can request cutouts for electrical outlets, notches for crown molding, or unique shapes like ovals and hexagons that aren't available in retail stores. Furthermore, ordering from a specialist allows you to choose safety backing—a film that prevents the glass from shattering into large shards if broken—which is essential for high-traffic areas or children's rooms.
