When Crick eyeballed Franklin’s x-ray diffraction image of DNA, he noticed that the picture implied a constant width and regular repeating pattern for the molecule.
Constant width, with base pairing, implies that a purine must pair with a pyrimidine, and never with another purine; similarly a pyrimidine can’t pair with another pyrimidine. These guys are different "widths."

G to C has three hydrogen bonds, and A to T has two hydrogen bonds so they cannot mismatch

purines are A and G and pyrimidines are C and T. Just like the other answer said they pair up because of the number of bonds, but it doesn’t have to do with being a purine or pyrimidine. a good way to remember that A and G are purines is the pneumonic "Pure silver." Purines are A and G or Ag (silver).
