Resizing Human Patterns for BJDs (DoA 2012)
DenofAngels Thread by EilonwyG
Transferring here for newer hobbyists. I am concerned that DoA will eventually become a dead forum result in link rot of a TON of useful and important information. Photobucket's purge has already done massive damage to the information that had been shared on DoA before 2015-ish.
All images from the original thread are gone.

I've had people questioning me for a while now as to how I've resized human patterns. There is a rather detailed tutorial that Dale Rae did on her web site - http://dalerae.com/enlargepattern06.htm
It is well done, but requires waaaay too much math.
I did try to use this tutorial, but decided there had to be an easier way. Through experimentation, I came up with this method. The beginning of the tutorial follows Dale Rae's instructions.
Take out the pattern instruction sheet, the first section if there are more than one in the packet.
We'll be dealing with the section where they have the pictures of the pattern pieces.
You'll need to scan the pattern pieces into the computer.
(They mean the images like this from patterns, I remember seeing this thread back in the day.)
Dale Rae's instructions call for scanning the patterns in at 125% to make it easier to work with. I've done the same, even though we won't be working with the pattern the same way she does.
Once you've scanned the picture in, you'll want to open it in a picture editing program. I use a program called Xnview. It's a free program you can find and download online. Personally I swear by it, but you can use any program that allows you to resize, cut and edit pictures.
If you haven't already increased the size of the patterns 125%, do that in the picture program.
Save the new size. Then cut each pattern into their own separate picture file and save it in its own folder.
There are a few pattern booklets where the instruction sheet has the pattern pieces at a much larger size than usual. If it appears that the patterns are on the large side, you can skip the increase of 125% step, as essentially, the pattern makers have done that for you.
This [125% pattern] will give you a basic size for a MSD scale 1/4.
You will need to tailor the patterns to the appropriate body, as it is not exact for Minifee, Kid Delf, Bobobie mini, Dream of Child, JID, or whatever mini doll. It just gives you the basic size to start from. [BJDs tend to have longer arms/legs. Take some measurements and add to the length and such!]
Once the mini size has been made, from there you create all other sizes you need.
SD Scale 1/3 or larger (+125% of the MSD size)
SD is 125% larger than mini (percentage found on another resizing thread on DoA about resizing existing doll patterns for other sizes).
As for those dolls over 60cm, use SD patterns and add length to arms and legs were needed, as most are not that far off in chest size for a complete resizing of patterns to be necessary.
Again from the mini size, resize the pattern 58% to get a Yo-sized pattern for Volks Yo, LTF, Bambicrony, Teenie Gems or other similar sized dolls.
Pukifee / Tinies (15cm) scale
From mini size, resize down to 35% for all Pukifee sized tinies.
For Cherishdoll Faith dolls (as I have two of them), resize to 52%. (They're a little smaller and thinner than yo dolls.)
I have not yet come up with resizing for Puki size or other in between sizes. For some, like Minoru world minis and Customhouse Petite Juniors, I would suggest starting with a yo pattern and adding in the length of arms and legs needed, as generally they can fit Yo clothes but are a bit tall for them. Same with 5star yos.
One thing I cannot stress enough is tailoring. As I said, this method will give you the approximate values for the pattern. Once you print the patterns out, I suggest cutting out a mock pattern piece in paper towels (the Viva paper towels are fantastic for this as they're much softer and closer to material) so you can then drape the patterns over the doll, figuring out where material may need to be subtracted or added to get the right fit. This way you won't waste valuable material on an outfit that may not end up fitting correctly. (This is something I did not do on my first outfit when I started sewing for the dolls.)
I would like to also stress that the instruction sheet patterns do not have any of the sewing markers that are generally on the actual pattern piece. You will either need to gauge the general area where these marks are located, or you'll need to consult the original pattern piece.
I have a variety of dolls and sizes in my collection and feel fairly confident that this tutorial covers most of the doll bodies out there. However, I do not own a doll from every company and there may be a few sizes I have overlooked. As I add to my collection, if I end up with a new type of doll body, rest assured I will come up with new numbers for resizing for that doll.
If you see any size not on this list that you would like to resize for, let me know and I can at least see if I have a friend who owns that type or similar for me to borrow and create a size for.
