Working a circuit out on paper first saves pulling jumper wires out later. This sheet prints five solderless breadboards down a page, each drawn the way the real thing is laid out: a pair of power rails along the top, rows A to E, the centre channel, rows F to J, and a second pair of rails along the bottom. The rails are marked plus and minus at both ends and drawn in red and blue, and the columns are numbered every five so you can transfer your sketch to the board hole by hole.
The dots sit at 0.1 inch - 2.54 mm - which is the pitch of every breadboard and of the pins on a DIP chip, so a 16-pin package straddling the channel spans eight columns on the paper exactly as it does on the board. US Letter gives 73 columns per board and A4 gives 71, with five boards either way. Draw the chips as rectangles, mark the jumpers between columns, and the layout you end up with is the one you can build.
The second layout turns the whole page into a plain 0.1 inch hole matrix for perfboard and point-to-point work, with every tenth hole drawn larger and inch markers down the left edge and across the top - 73 by 96 holes on US Letter. Both versions derive their spacing from the real inch and are centred with equal margins, so printed at 100% a ruler agrees with the pitch.
