What I do:

1. Open image in GIMP
2. Select Image/Canvas Size
3. Enter something like width 700 and height 500 in the size boxes, and then click the link icon to lock the 
aspect ratio. Then enter the true height of your image in the Height box.
4. Use Offset settings or Center button to align your image on the canvas as required.
5. Choose Resize Layers, All layers. Choose Fill With, Background Colour (or whatever).
6. Click Resize.

If you want to align a layer with the edges of your canvas, or centre it on the canvas horizontally or 
vertically, take a look at the Alignment tool (it’s in the default toolbox, at least on my OS/X download).
