When deciding what length drawer slides you require you need to first identify the maximum depth available and secondly decide what extension works best for you. Typically speaking you want at least seventy percent of your drawer to extend to make it of any real assistance. This means if you have a 1000mm carcass, you would be aiming for a slides 700mm or longer.
Drawer slides get weaker as they get longer, so sometimes getting shorter slides is a great comprise between the extension you require versus the load you need to carry. Another benefit of reducing your drawer slide length is shorter slides cost less.
It all boils down to what you are putting in your drawers. If your drawers are going to be full of little boxes you will need the whole thing coming out so you can clearly see what you are looking for. If your drawers are for larger boxes, duffle bags or even say a shovel then you really don’t need to see the whole thing to know what you are grabbing.
