Ideally, figures that are 2 1/2 inches and under would work best for the model. Some of the Tyco figures I have, while they look good for the most part, are slightly too big. Big Bird is a tad over 4 1/2 inches, which is managable, given that he's Big Bird, but some of the figures that are 3 inches or over (Count, Telly, Bert, etc) seem un-naturally massive within the model.
