![]() which can be done fairly easily in the head! I’ll come back to why they’re written this way (at least, when using metric) later. ![]() If that’s still way too big for your purpose, it is just as easy (if you normally use centimetres) to calculate ‘tenth of the size’ by moving the decimal point of each original measurement by one place or ‘hundredth of the size’ by moving it a further place. You can even quite easily arive at ‘twentieth of the size’ by moving first the decimal point one place then halving! So already you’ve got the choice of four possible scales. If you’re new to it, you can for example decide to make a model or a drawing of something using a simple reduction that can be calculated pretty much in the head, such as ‘half the size’, which means you only have to divide each measurement of the original by 2 (or in other words ‘in half’). What I’ve often found is that although the principle of reducing an object in size is a very simple one, many people who haven’t done it before may assume it’s more complicated than it is. That version may have been updated or expanded since.įor those who are new to working in scale and need some basic advice or just a simple explanation before starting, here is an overview. Please note before you start reading this older post that I have long since included a version in my Methods section which can be accessed above. ![]()
