Before starting to build one, if you’re not familiar with my methods, take a look at 10th Anniversary Populist Plans for the basics of building cameras from cardboard.There are two templates for the Pinhole Lab Camera. One makes negatives an eighth of a standard sheet of photographic paper, (2.5 x4 inches, 64x101m), the other a quarter sheet of paper (4x5 inches, 102x127mm). Here is the link to the templates

assembled in alignment
The material for making the camera is the sort of cardboard from cereal boxes or cartons of beverage cans. It has to be something that will fold. Remember to roughen any glossy surfaces that will be glued.
I’ve set up both of them to print on U.S. Letter paper which should fit on A4 as well. (Make sure to print at 100% and not fit to print) This required the top and bottom boxes of the camera to print on multiple sheets of paper. The templates need to be assembled in alignment when glued to the cardstock as illustrated to the right. With the 2.5x4 camera two pieces make up the top and bottom and with the 4x5 camera, four. The edges which go together are labeled with letters.
The pictures below were done making several different cameras.
Start by cutting and folding the bottom box.
Before gluing, cut out the opening for the pinholes.
One at a time, glue the sides. Make sure they are straight and the inside flaps meet in the center and clamp them.
Your clamps will probably not reach all the way to the bottom of the box, particularly with the 4x5 camera. Use a piece of double weight card stock slightly wider than the camera to hold the bottom of the sides tightly together while the glue dries.
