Help with calculating evenly spaced increases and decreases

Sometimes patterns instruct you to make evenly spaced increases and/or decreases. But what does this mean? How many stitches do you have to make before you make the increase/decrease? And why does the pattern not just state the amount of stitches?

One of the most important reasons – at least for me – is to keep the pattern simple and easy to follow. Garment patterns often include multiple sizes. The pattern would become a total mess without clear overview if all the increases/decreases were included for all sizes. In order to make it easier to follow and not make you feel lost, the pattern is written in a shorter way.

Example: my Simple Dress to Impress uses this way of formulating the increases/decreases
Simple Dress to Impress - free crochet summer dress pattern - using evenly spaced increases and decreases

So here is how to calculate evenly spaced increases / decreases

It’s quite simple to calculate how many increases/decreases you need to make. All you have to do is divide the current number of stitches by the number to be increased/decreased. Let’s say you have 186 stitches and you need to decrease 8 stitches to get a stitch count of 178 st. 186/8=23.3.

You obviously can’t decrease every 23.3 stitches, so we round the number down to 23, which means you need to crochet together every 22nd & 23rd stitch. However, you’ll notice you will end up with 176 stitches (23 x 8 – 23 = 176) instead of 178 because of rounding it down. Therefor you need to add a couple of extra decrease in there by working the 23rd & 24th stitch together. Don’t worry, a few unbalanced stitches like this is not going to be visible. Just focus on getting the correct amount of stitches.

If you have 186 stitches and you need to increase 8 stitches to a total stitch count of 194, you will have to increase at every 23rd stitch (186/8=23.3). However, 23 x 8 + 8 increases = 192 and we need 194 stitches, so in this case you would need to add two extra increases. You will need to add a few more increases every here and there to get the correct amount of stitches.
