You can purchase similar boards in different sizes. For what I do I like this particular size in both single and double sided forms. The price of the board is decent if you buy 5 at a time and gets even better if you buy 10. Whatever size you buy, make sure the copper pads are tinned. I bought a few boards with copper pads and some others that looked gold plated but weren't and I found it very difficult to get the solder to stick even after polishing them with a spoked wheel using a dremel. They can easily be cut to smaller sizes. Use a sharp metal scriber (not an Xacto knife - they tend to go their own way) and a metal ruler to draw a deep line where you want to break the board. Then place it on the sharp edge and snap along the line. (I prefer to bend the board with pliers because it clicks cleaner and is probably safer.)
