How to properly attach a mirror to a plasterboard wall?


I'm in a bit of a mess as I do things around the house much less often than I actually should so I thought home of the DIY will be the right place to ask for this.

I've purchased a large mirror for my room and realized that I don't have any wall plugs that would be long enough to reach the load-bearing wall and I've never used wall plugs for the plasterboard wall in front of it.
To be honest I have no idea which ones to buy.

How much weight the plasterboard wall ones handle. And is it even a good idea to them or should I just get longer ones which will reach the load-bearing wall?

Thank you for your time,

As Canucksgirl writes, the plasterboard, sometimes referred to as drywall is only made up of some cardboard with compact lime type powder in between, so it will not bear much weight at all. BUT, if you can find the studs used to attach it (and many times there are more studs along the wall behind the plasterboard) you would nail/screw into them. One way that is kind of hit or miss is to get a stud locator (most of the cheaper ones use a magnet to detect nails behind the plasterboard). If your walls follow any kind of building code, they should be located equal distances apart, so once you locate one, you can measure to find the others.
I'm a little confused by your question... You said you bought a mirror and don't have any wall plugs that would be long enough to reach the load-bearing wall?

A load bearing wall is one that carries the load of your ceiling. A non-load bearing wall is an interior wall that is not required for structural support. In both cases, the walls are constructed with framing studs (most often they are wood, but in some cases they are metal or possibly other materials) and then covered with drywall.

To install a mirror, you want to locate the framing studs within the wall and screw the mounting brackets, (used to hold the mirror) directly into the studs. A strong adhesive (used for mirror installation) should also be used and can be purchased from most home improvement stores. If you are unable to secure the mirror into the framing studs and its a heavy mirror, then you may need to add some reinforcements to the wall. This can be done by removing some of the drywall and securing a horizontal 2 x 4 between the vertical framing studs. Then you can secure the mirror directly to the 2 x 4 without any fear that it will fall down.

Get a picture of the mirror, figure out how much it ways , ad hie to the local Ace. There are LOTS of ways to solve the problem and the fellow there can instruct you. And you will learn a lot just looking around. A hardware store is not like a grocery store; you are noit expected to come in knowing exactly what you want. You walk in with a problem and leave with a solution.

The cleanest-looking (but actually messiest) way would be to apply LOTS of silicone on the back of the mirror and just stick it to the wall. Of course, the feasibility is hinged on the weight of the mirror and if you own the place.
