Are you choosing figures for an arts and crafts project?It may surprise you to know that the average size of an N gauge figure is just 1cm tall, great for N gauge model railways, not so great for larger arts and crafts projects. You can discover a great range of taller figures by searching for OO gauge figures (twice the size of N gauge) or O gauge figures (four times the size of N gauge).
