Scale Charts and Scale Tools

It is difficult to label our trees with a scale because as you can see from the website our trees range in size and shape to fit a variety of scales. From T scale to O scale we have trees to enhance every project; a tall deciduous giant tree in T scale works well as a small bush/ shrub or sapling in N, OO or HO scale. Using your imagination, build hedges, ground cover, orchards and forests with our wide variety of shapes and colours. There are plenty of online scale calculators that work fine - if you still aren't sure please don't hesitate to contact us!

Model Tree Scale Charts

Use the scale charts below to determine the correct tree size for your next model project or diorama.

For ease of working 1" = 25mm as near as workable I.E 100mm = 4", 3" = 75mm etc.
