Country scenery background sheets can be used with many different scales and sections can easily be cut to add or mask features as required.
Town and city scenes may need more attention to scale to be effective. Where these are made for a particular scale this is shown, with OO suitable for 1/72-1/87 scales and N for 1/140-1/160 scales
Peco produce identical sheets in three sizes, allowing additional depth to be portrayed by forced perspective. Foreground buldings on large sheets are scaled for OO model railways, N gauge modellers may need to use medium or small sheets instead.
