Easy Pattern Grading – the “quick and dirty” method
By special request, here’s a very quick little tutorial on how to grade a pattern to your size!
There are obviously a number of methods for pattern grading. The most professional and accurate is probably the slash & spread method. But I find this a little painful as it takes more time, and involves cutting the pattern in numerous places and shifting it out.
My preference if I’m short on time, and I’m not worried about it being “perfect” is to simply shift the pattern, tracing as I go. I know it probably isn’t the most “text book” method, but it’s easy, fast & it works…
For this tutorial I am using the example of a pattern I recently graded down.
Determine how much you need to grade your pattern by. Compare your measurements to the pattern’s. As a side note, my pattern was a size 14 to fit bust 36”, which would appear to be perfect for me as I have a 36” bust.
But I find that commercial patterns have too much ease for my taste, so I always go down a size. So I wanted to grade down to a size 12, ie 34” bust. Which meant I needed to grade down by 2”. Divide this measurement by 4 to determine how much to shift each pattern piece. For me this was ½” (ie 2 divided by 4)

Lay the pattern piece on some pattern paper (I’m using the bodice front), and trace the centre & bottom edges.
Then shift the pattern outwards by ½” from the bottom right corner edge
Trace the rest of the pattern
Neaten up the edges, and now you have a smaller bodice front pattern. Follow the steps for the other pattern pieces as well, and then you are done!

Note:
- If you need to grade the pattern by an uneven amount (ie the difference between your size and the pattern is not the same in the bust waist & hip- this is probably the case if you are pear shaped), I find the easiest way is to separate the pattern & grade the areas separately, then blend the two sections together
- Another thing to keep in mind is your cup size. Commercial patterns are based on a B cup, so if you are smaller or large than that, you will probably need to do a bust adjustment (not covered in this tutorial).
- Also this method is just as easily adapted to grading a skirt or any other pattern piece
