SY1720 Wall Mirror: a 100cm circle and the wall it needs
This guide is about
SY1720 Wall Mirror
A circle behaves differently on a wall from a rectangle, and the difference is worth understanding before you buy one. The SY1720 Wall Mirror is listed in a single size, 100cm across, with a border made of separate mirrored segments rather than one continuous frame.
What a 100cm diameter actually occupies
A circle only reaches its full width at one line across the middle. Everything above and below that is narrower, which is why a round mirror sits in a space an oblong of the same width would crowd. On a wall between two doors, in a stair return, or above a radiator with a shelf over it, the curve pulls away from whatever is beside it instead of running up against it.
The trade-off is in what you can see in it. A 100cm circle gives you a metre of glass at its widest point and much less at the top and bottom, so it is better at reflecting a room and light than at showing you a full standing reflection. For the second job you want the long side of something oblong, like the 120cm face of the SY1719 Wall Mirror.
The furniture widths it suits
| Furniture below | How a 100cm circle reads |
|---|---|
| Under 100cm | Too wide. The mirror overhangs and the pair looks unbalanced. |
| 120 to 140cm | The comfortable range. Clear furniture top each side of the circle, and the two read as one group. |
| 160cm and over | Works, but the circle starts to float. Flank it with a pair of lamps or a tall object to hold the ends down. |
On a bare wall with no furniture under it, treat the centre of the circle as the line to set: around 155 to 160cm from the floor keeps it at eye level for most people. Hung higher it stops being usable as a mirror, which is a legitimate choice if what you want is the reflected light the description talks about.
The segmented border, and the one thing it makes fussy
Because the border is partitioned rather than smooth, the joints between the segments show at the edge. That is the look, and it is the reason this mirror reads as an object rather than a hole in the wall. The listing does not say how many segments there are or how they are spaced, so the photographs are your only guide to that. It also means it needs hanging straight: a plain circle hides being a degree out of true, and a divided border is less forgiving, because the eye picks up the joints and uses them as a spirit level. Mark both fixing points, check across them with a level, and do not hang a segmented circle from a single nail and hope.
What the listing does not record
- Weight. Not given, so there is nothing on the page to size a fixing against. Ask us for it before you fix this to plasterboard.
- Depth and fixings. Neither the projection from the wall nor the hanging arrangement is described. Ask what is on the back.
- Materials. The border is described as mirrored and segmented; what sits behind the glass is not stated. The three photographs on the product page are the clearest guide until you ask.
- Moisture. No bathroom or steam rating is recorded, so check with us if that is where it is going.
