Keep in mind that a "perfect" rectangle will only be perfect within a given coordinate reference system. If you change the CRS, the rectangle will warp.

I tried the suggested solutions but found the CADTools plug-in a bit too complicated to get a quick hang of it. Besides, this is a rather simple task.
Instead I found the plug-in Rectangles Ovals Digitizing by Pavol Kapusta. The name is rather self explanatory and it works excellently. You can draw shapes from centre or by extent.

I've tried it with Windows 7, Ubuntu 12.04 and Ubuntu 10.04 now, both with and without OpenLayers Bing Aerial to digitize from. The tutorial site is an excellent resource with a video showing a user clicking the tool, then digitizing a square with perfect 90 degree angles locked in. Could someone else make an attempt to see if it works for them? Sorry it took so long to get back on this.

In order to create polygons or lines with specified lenghts en angles you need to enable the advanced digitizing panel. (View--panels-advanced digitizing)
Just add vector layer (lines or polygons) start editing and add feature. In the advanced editing window you can specify the angles and/or distances. To finish the sketch, click right mouse.

In order to create polygons or lines with specified lenghts en angles you need to enable the advanced digitizing panel. (View--panels-advanced digitizing)
Just add vector layer (lines or polygons) start editing and add feature. In the advanced editing window you can specify the angles and/or distances. To finish the sketch, click right mouse.

I tried the CADtools but I found it a bit complicated. Besides, this is a rather simple task.Instead I found the plug-in Quantum Aided Design(cad like commands in QGIS). The name is rather self explanatory and it works excellently. You can draw/edit/copy/ trim or offset etc..

Keep in mind that a "perfect" rectangle will only be perfect within a given coordinate reference system. If you change the CRS, the rectangle will warp.
