The Apple Watch Solo Loop sizing effectively maps to the holes of the Sport Loop, according to John Gruber. The distance between the holes in every Apple Watch Sport Band is reportedly exactly the same as the distance between the 12 sizes of Solo Loops on Apple's measuring tool.
All Apple Watch Sport Bands have seven holes. For the 38mm or 40mm band, the S/M band corresponds to the Solo Loop sizes of one to seven, and the M/L band corresponds to the Solo Loop sizes of four to 10. For the 42mm or 44mm band, the S/M band corresponds to the Solo Loop sizes of three to nine, and the M/L band corresponds to the Solo Loop sizes of six to 12. Gruber writes:
A few people have wondered why Apple doesn't just map fluoroelastomer Sport Band sizes to Solo Loop sizes. I can see why Apple doesn't do that — they can't assume everyone already has access to an Apple Watch with a Sport Band, and even for people who do have access to one, Apple can't assume it's the right size watch (38/40mm vs. 42/44mm). And to further complicate matters, each Sport Band comes with two sizes for the side with the holes: "S/M" and "M/L." So that's four separate mappings from Sport Band holes to the new Solo Loop sizes.
The below image shows size mapping for two 40mm Apple Watch Sport Bands, with S/M and M/L sizes.
The following image shows size mapping for two 44mm Apple Watch Sport Bands, also with S/M and M/L sizes.
The news that it is possible to match Solo and Braided Loop sizing to the Sport Band will reassure many existing Apple Watch users who have been concerned about sizing issues and the potential need for an inconvenient return.
Regarding Apple's measuring tool, Gruber points out that "I think you're supposed to use the tool to precisely measure the circumference of your wrist, not to simulate the circumference of what you think would be a comfortable watch band," and he believes this may be the result of much of the discontentment about Solo Loop sizing.

Apple turns 50 this year, and its CEO Tim Cook has promised to celebrate the milestone. The big day falls on April 1, 2026.
"I've been unusually reflective lately about Apple because we have been working on what do we do to mark this moment," Cook told employees today, according to Bloomberg's Mark Gurman. "When you really stop and pause and think about the last 50 years, it makes your heart ...

Apple recently acquired Israeli startup Q.ai for close to $2 billion, according to Financial Times sources. That would make this Apple's second-biggest acquisition ever, after it paid $3 billion for the popular headphone maker Beats in 2014.
This is also the largest known Apple acquisition since the company purchased Intel's smartphone modem business and patents for $1 billion in 2019....

Apple plans to announce the iPhone 17e on Thursday, February 19, according to Macwelt, the German equivalent of Macworld.
The report, citing industry sources, is available in English on Macworld.
Apple announced the iPhone 16e on Wednesday, February 19 last year, so the iPhone 17e would be unveiled exactly one year later if this rumor is accurate. It is quite uncommon for Apple to unveil...

In the iOS 26.4 update that's coming this spring, Apple will introduce a new version of Siri that's going to overhaul how we interact with the personal assistant and what it's able to do.
The iOS 26.4 version of Siri won't work like ChatGPT or Claude, but it will rely on large language models (LLMs) and has been updated from the ground up.

The process for this thing is way too complicated, especially right now.
Beyond that, he's probably correct that this was intended as a wrist-measurement tool and that people are (understandably, but probably incorrectly) using this instead to interpolate what they believe a correct band size will be. In short, there's almost certainly a communication failure at work here.
I can confirm that this is true for me. I got a size 7 band that fits perfectly, and I’ve always used the second hole (from tightest) on my sport bands. (44mm)
What a great idea to release a brand new product in 12(?) brand new sizes while stores are closed so that basically no one can try them on either.. Guess the delivery people won't be out of a job anytime soon at least :)
