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 scale or HO scale. Using your imagination, build hedges, ground cover, orchards and forests with our wide variety of shapes and colours. If you prefer you can always use Scalecalc

ScaleCalc is a simple calculator for scale model fans. ScaleCalc simplifies estimation of the model's size when the prototype sizes are entered.

With Scalecalc you can:-
· Calculate dimensions of the model (replica) when prototype dimensions are given.
· Work in fractions or decimals

· Calculate sizes from millimetres up to miles!
· Work in scale values or calculate the scale

ScaleCalc is a freeware program which we believe to be 100% CLEAN, which means it does not contain any form of malware, including spyware, viruses, trojans and backdoors, however as with all software please scan before use.

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.
