Generally, I don't take boobpedia too seriously. While most sites exaggerate girls' heights and only a few get them right most sites get boobs right and only boobpedia exaggerates them. (Boobpedia also gets heights and weights wrong, they really just make stuff up.) in this case though they seem to be not far off.

I personally use Boobpedia and cross-reference with Freeones. If they're only a size or two apart, I'll use the one with most recent citation (or largest).

Here's something to factor in when looking at breast size. The larger the band number, the smaller the letter size will appear. As one woman told me, a rudimentary shorthand says that for the loss of every two inches of band, cup letter increases by one. So a 32D is roughly equivalent to a 30E. This isn't an exact science though as some women prefer a tight band size whereas others might like theirs looser.
(A good way to think of it is to consider the letter as the volume and the band as the distance that volume has been stretched).

Marina Diamandis is a 30G whereas Esther is a 34F, but if both Esther squeezed and Marina upsized to a 32 band, their resulting respective sizes would be Esther 32G and Marina 32F. Compare Sarah Nicolla Randall with a natural size of 32I, now only two cup sizes larger than the compressed Esther. Still a fair gap, but not nearly as large. You also have to factor in BMI and hip-waist ratio. A plumper, more diffuse fat distribution usually results in softer breasts when compared to the classic 'slim-and-busty' models. You could cite Venera Isabella as an exception to the rule, but note that her breasts seems to have an uneven distribution of weight appearing somewhat stretched.

To return to Esther vs Sarah, note that while both women's breasts have a good amount of lift in respect to their size, Esther's breasts are often portrayed as full and 'pushing' against the fabric whereas Sarah's are usually 'squashed' flowing around the fabric as opposed to bulging against it like Esther's pair.

Did someone say; "Stacey Poole, Joey Fisher, Alice Goodwin, and Beth Lily"??

Alright here's a rundown of sizes along with a rough cup conversion to match band size.

Esther Baxter: 34F
Sarah Nicola Randall: 32I > 34H
Bethany Lily: 32H > 34G
Alice Goodwin: 32E > 34D (Silicone)
Joey Fisher: 32H > 34G
Stacey Poole: 34G

After calculations, everyone outsizes Esther by a cup size (except Alice Goodwin who falls short by two, and Sarah Randall who exceeds her by two). But like I mentioned earlier, there's more to it than just size. Shape, suppleness, and sensitivity all need to be factored in.

While uber-buxom, Sarah Randall's breasts have been shown to be quite malleable, both in her pin-ups and from her photoshoot videos. Likewise, from images alone Joey Fisher set seems to be similarly soft. I'd rate that Stacey Poole rates about average when it comes to pliability, but when you look at Esther's pair, it's clear that she's batting above average. Resilience wise, I'd say that only Bethany Lily and Alice Goodwin are of equal standing to Esther... Alice, solely because her breasts are artificial, which brings up the sensitivity issue.

Enhanced breasts are far more fragile than a natural set, mostly because instead of natural padding behind the skin, there's silicone. Which, while it had a fair amount of give, is more often than not, situated right behind the skin for a more rounded and shapely look. Aesthetically pleasing, it also means that you have to limit your movements else you'll aggravate yourself just by bouncing.

All in all, I'd say that by dint of their size and suppleness, only Bethany Lily and Sarah Nicola Randall would be a match for Esther Baxter. Not a runaway in their favor, but a fairly equal pairing. Bethany has a slight size advantage and equivalent suppleness (though her youth and inexperience may be to her detriment) whilst Sarah's monumental size advantage is mitigated by her incredible softness (a melons vs pillows scenario).

As an after-note, I've read a few sources that seem to indicate that Esther is larger than her cited size of 34F, which is seemingly substantiated by images of her breasts appearing to bust out of her attire.

All of those sizes look about right to me except Esther.  Esther may have been a 34F years ago, but she's MASSIVE now.  I think Esther and Sarah are about equal and on a totally different level from those other girls.  Stacey, Bethany, and Joey are a level or two down and all about equal.  Then there's Alice Goodwin (bless her heart) who really shouldn't be in the same conversation as these other girls in terms of size.

[MisterSteel]

I dunno, I wouldn't quite call Esther's pair equivalent to Sarah's just yet, but I'd rate her at being at least a cup size larger than the 34F she's billed. At least. Comparing her to Beth, Joey, and Stacey (who all are or equivalate to a 34G) it looks like Esther has them beat by about a cup, putting her at 34H. Perfectly midway between the trio and Sarah. And again, size isn't everything; shape, firmness, and sensitivity are also important factors.

Heh, maybe Esther is purposefully billing her as smaller than she really is to bait over-endowed girls who think size is everything into challenging her.

Being from the South in the USA I don't follow the British cover girl scene much - but that Beth Lily is something! She and Ester must meet at some point - it's like Lex Luthor and Superman!

[FomaTatulyan]

Beth Lily is huge. Esther is the only girl in this thread that hasn't gone topless. Too bad we don't have photos/videos of her to compare to the other girls. We can really only make educated guesses.

[MisterSteel]

Sorry to resurrect this thread after so long, but I just realized that no one answered the initial question; Who has the tits to compete against Sarah Nicola Randall?

Freeones bills her at 32H while Boobpedia bills her at 32I.

Going off the later (using the largest recorded size of each model to keep things fair) I'd say that five VERY viable contenders include;

Kristina Milan - 40J (Supple yet surprisingly heavy looking. As a bonus, she's recently been shown lactating.)
Wendy Fiore - 32K (The only non-topless contender on this list, but from what we can see, she might have the pertest orbs on the lineup.)
Hitomi Tanaka - 32K (Straight from Japan, probably the biggest if not the best breasts hailing from Asia.)
Maserati XXX - 36K (A little soft but still quite shapely when you factor in that she's buried some of the biggest dicks between them.)
Rachel Aldana - 30N (Probably the largest natural pair out there at the moment.)
