It's pretty simple to use .. on the left size is the block size you have - on the top is the size you want. To enlarge a block - find the block size on the left side of the chart and find the size you want on the top .. where they intersect is how much you need to increase or decrease by ..
For example .. 3" block to a 4" block - find both and you will see 133% that means that you need to increase your block size and all pieces 133%
5" block to 3" block - find both on the chart and you will see 60% - that means that you decrease all block pieces 60%.
