My guess for Blaze The Cat's BWH is 53/40/56 - 20A.

But, getting there was another tale...

When you work with fictional characters, you often find that taking measurements is only as good as the proportions the artist used. Which means everything is part science, and part art. The more liberties the artist used, the more we must play with our numbers to achieve something believable.

We saw a bit of that with Amy, and we see even more of that with Blaze.

Our process began as the others did. I found promotional art for Blaze the Cat. This was on one of the Sonic wikis. But, I believe this was the same art that appears in the title screen, and manual... just for reference.

Likewise, we grab her numbers off one of the wiki results in a quick web search... 95cm and a range of weights (it says between 24kg and 29kg.... Well... that's less helpful... ... ... I just decided to go ahead and move forward and worry about that part later).

So Anyway, we took her measurements:
- Height: 1392 - 95cm
- Bust: 188 / 1392 X 95 = 12.83 X 3.14 ~= 40.28cm ~= 15.86”
- Waist - 158 - 158 / 1392 X 95 = 10.78 X 3.14 ~= 33.86cm
- Hips - 182 - 182 / 1392 X 95 = 12.42 X 3.14 ~= 39.00cm
- Under-Bust: 180 / 1392 X 95.= 12.37 X 3.14 ~= 38.85cm ~= 15.30”

Uhh … AA?!?!

I suppose... She is described as small chested... But, I don't think so.

So we grabbed a different piece, and tried to see if we could make a ratio to find her chest . In this case, I found a picture of Blaze in her Ice Skating outfit from the Tokyo Games. And get our ratio and new measurements:
- Ratio: 69 / 78
- Under-Bust: 40.28 X 69 / 78 ~= 35.63cm ~= 14”

It's not great... I mean it makes her Bra a 14B, which is a bit big, in my opinion.
Still, With all those measurements, we scaled everything up:
- Scaling factor: 1.442105263157895
- Scaled Height: 137cm
- Scaled Weight: ??? 24? 35kg?
- Scaled Bust: 58
- Scaled Waist: 49
- Scaled Hips: 56

I punch the Height and BWH into the body visualizer... and immediately get treated with nothing but a massage chasting me for using an unhealthy BMI.

That means my numbers are too small... and so are probably not correct.

Well, we just try out fallback from when we did Amy. Blaze is 15, so our 6.5 factor should, in theory, work even better.

It didn't... Behold:
- Height: 683 - 82cm
- Bust: 188 - 188 / 683 X 82 =  X 3.14 ~= 22.57 X 3.14 ~= 70.87…. That's bigger than Rouge!!!!! No blinking chance!

Well... We backtracked, and grabbed one of the pictures of her from Sonic 06 (pulled from the wiki). And measure it out:
- Height - 679 - 95cm
- Bust - 93 / 679 X 95 ~= 13.01 X 3.14 ~= 40.86cm
- Under-Bust - 87 / 679 X 95 ~= 12.17 X 3.14 ~= 38.22
- Waist: 79 / 679 X 95 ~= 11.05 X 3.14 ~= 34.71
- Hips: 104 / 679 X 95 ~= 14.55 X 3.14 ~= 45.69

And fail in the exact same way. It's basically the same numbers we just got.

I then scratched my head for quite some time. And finally came up with a plan B (or C, depending upon how you count it).

I would just make a ratio of Waist to Height using one of the samples, and then multiply that by 137 to get the waist we will punch into the Body Visualizer... And do something similar for the other numbers (Bust / Waist, and Hips / Waist):
- Waist to Height Ratio is 0.368. 0.4 is minimum healthy. But, it’s close enough. -- So let’s make the modeler say 50cm.
- Bust should, therefore be : 41 / 35 X 50 ~= 59cm
- Hips - 46 / 35 X 50 ~= 66cm

I saw the numbers got bigger, and then felt my heart drop, when I saw BMI message again.

Considering this was my plan B, I just tried the same approach but factored out her head:
- Waist-to-Height Ratio - 34 / 82 ~= 0.415
- Scaled Waist - 137 * 0.415 ~= 57cm
- Scaled Bust - 41 / 35 X 57 ~= 67cm
- Scaled Hips - 46 / 35 X 57 ~= 75cm

Everything is going good, even the weight... until we lower the hips to 75. Then, it immediately gives up.

Which means her hips are too small. I, then, decided to just raise that number up till we hit the minimum scaled weight of 35kg.

Which yielded a result of:
- Scaled Bust - 67cm
- Scaled Waist - 57cm
- Scaled Hips - 83cm

The Bust and Waist looked good. But, the hips look too wide. Blaze is definitely more of an Hour glass, than a Pear.

And now, I hit the point where I had to get "artsy"... Specifically, we are going to use the, good old, "guess and check" method.

Looking at Blaze, her waist is pretty comparable to Amy Rose (possibly a little smaller, but not that much).

So, I choose to hold that number as is, and play with the other numbers until I get a weight in the 35kg to 42kg range (a scaled version of 24 to 29kg).

And I arrived at a new scaled number:
- Scaled Bust: 76cm
- Scaled Waist: 57cm
- Scaled Hips: 81cm
- Scaled Weight: 37kg

So we Scale that back down:
- Bust: 76 / 137 X 95 ~= 53cm ~= 21”
- Under-Bust: 21 - 1 = 20” ~= 50cm… bumping up to 51 as it was -2 before.
- Waist: 57 / 137 X 95 ~= 40cm
- Hips: 81 / 137 X 95 ~= 56cm
- Weight: 37 / 137 X 95 ~= 25.66kg ~= 26kg.

And we arrive at my final guess for Blaze The Cat's BWH, which would be 53/40/56 and a Bra size of 20A.
