Using small graphics

[Glenjamin]

This may not be entirely an AGS-based question, but it still counts.

Due to my game's art style, my sprites are extremely small. So small that the backgrounds don't even fill half the room area.
What is the most efficient way of making them more workable? Is there an in-engine way of doing this? Or should I just double the size and keep the aspect ratio? Thanks!

Do you mean that you want graphics half size (or less) of the smallest resolution supported by current version of AGS?

If you wish to stick to the latest official version, only suggestion would be to scale your graphics up using nearest-neighbour method (to keep them pixely).

Or you could try out a newer WIP version of AGS 3.4.0 found here:

AGS 3.4.0 supports literally any resolution, so you can choose the smaller one to make your backgrounds fit right in.
