Here are some guidelines:

If you’re working with a large wall and have the floor space, make some decisions by arranging the artwork on the floor first. You can also measure how far they need to be from one another. Then take one at a time and put them up on the wall.

If for some reason you can’t put artwork on the floor, make a template of each piece you’d like to hang. Trace around the outside of the frame on kraft paper, cut out the shape, and label it so you’ll remember which piece it represents. Also draw an arrow on it so you know whether the art is vertical or horizontal. Secure the templates to the wall with a product known as reusable adhesive, which looks a bit like putty or chewing gum. It won’t tear pieces from your wall or the paper patterns.

Figure A
Consider grouping four small same–size pictures together in a four–square, to give the illusion of a larger picture (Figure A).

Figure B
You don’t always have to have four in a group. Consider using a larger picture in the center. Then place two smaller pictures on either side of the large picture, spaced vertically to about equal the length of the larger frame. Or, in place of the larger picture, use a large mirror (Figure B).
