Was recently looking for differences between echo fighter characters and who they echo, and was especially intrigued by Peach and Daisy. Admittedly, I haven't played either of them much and never quite got the hang of Peach in prior games, but I've tried them some and wanted to know what advantages or disadvantages one had over the other. Skimming this thread, I didn't see that anyone had labbed how their height differences affect their hurtbox. So I ran a few crude tests with some screencaps I can share at the end.
To start with, their height differences aren't as significant as they might appear due to Peach's taller crown. Using the training area's grid system, that we'll assume is metric, here's what I found...
- Daisy's height to the top of her head is 160 to 165 centimeters. Occasionally she can appear taller during idle animations, but that's her general height. Using the green invincibility highlight after an SD, which has been said to actually show a character's hurtbox (and if we assume it does)... her hurtbox height is between 162.5 and 167.5 centimeters. Basically the top of the hurtbox seems to be about a quarter of a decimeter or 2.5 centimeters above the top of her head, bisecting in half her crown jewels visually.
- Peach moves a lot less than Daisy at a standstill and her height appears to be a more static 166 to 167 centimeters. Using the same method to view the supposed hurtbox area on Peach, it can be seen that the green area at it's highest point is also about 2.5 centimeters above her head. Again, this happens to bisect the crown jewels visually on her taller crown. Which is to say, her hurtbox appears to be nearly 170 centimeters tall.
TL;DR -
Peach is taller visually, and assuming the invincibility display shows the hurtbox, that height is proportional. So in theory, Daisy's marginally shorter hurtbox should mean that she should duck under hitboxes that hit Peach by just a literal hair.
...
And yet after repeated testing, I've had a hell of a time trying to hit Peach with something that wouldn't hit Daisy too. First of all, it's hard to control an attack that precisely. And secondly, Peach and Daisy are on average less than half a grid width in height difference and can be nearly the same height depending on what their standing animation has them doing, not even including special idle animations. Even if they were always half a grid width in height difference, that would still be a hard window to hit.
Even so, I repeated my tests a few times and as far as I can tell... they're effectively the same height. That's my conclusion and I'll share my evidence in just a sec.
First to explain the test. I decided to use Falco's lasers since they're narrow and fly perfectly straight. The best I could manage was shooting at half grid intervals, or intervals of 5 cm. For instance, a laser shot at 220 cm, 215 cm, 210 cm, etc going down until I hit my target. I could not seem to hit quarters or 2.5 cm increments so already that could be the difference between hitting Peach but not hitting Daisy. I used the narrow tail end of the laser to more precisely determine it's height since the laser itself is more than 10 centimeters thick at it's thickest point. Anyways, shooting 5 cm lower each time, I "sparked" Peach and Daisy at the same time with a glancing blow. Here's the evidence...

Excuse the low res, this was done in handheld.
Anyways, using the meter markers and counting the mark just above the bottom of the platform as "0", both Peach and Daisy had a glancing blow effect from a laser shot at a height of 2.05 meters (205 centimeters). At 210 there was no spark effect and at 200 they both took a laser hit. The platform effectively adds 25 cm to Peach and Daisy's height from the 0 line, so at ground level this is a height of 180 centimeters for the glancing blow effect, 185 to clean miss, and 175 to hit them.
In the screencaps, you can see that the top of Daisy's head (or rather hair) is just below a grey line marking 190 cm. The line is never obstructed by her hair but is kinda sitting right on top of her head. Peach, on the other hand, has her hair obstructing this same 190 cm line. Top of her hair seems to be about 192 cm maybe. The difference in Peach and Daisy's heights in this instance looks to be about 2.5 cm or maybe just within that, tho both their hurtboxes activated a glancing blow. I can only conclude that the laser hitbox doesn't bother with calculating below 2.5 cm differences and just hits anything within a window that size, or the supposed hurtboxes seen during an invincibility display aren't that accurate to the true hurtbox space... perhaps a bit of both.
In any case, this was always going to be a very marginal difference but it seems perhaps too marginal to make any difference really. But it was a fun experiment and I'm happy to share it and talk overly much and overly seemingly seriously about it, heh.
Btw, for anyone interested, I have screencaps of the appearance of their supposed hurtboxes using the invincibility display too. I just chose not to share them here since they're easy enough to witness on your own. Simply turn on the invincibility display, frame by frame speed, and then SD and jump from the platform in time to see your hurtbox while your character is standing upright post-landing animation. Full zoom helps too if you want to see the details of the space it contains. Again, assuming this does represent the hurtbox. I'm trusting in what I've read and heard about this trick.
