Jubilee Bracelet Length

[Scott6113]

I ordered a 126333-016 41 Datejust gold/stainless, fluted bezel, jubilee bracelet, white face, a couple of weeks ago. I asked the AD if I should order additional links since I have an 8" wrist. He said that they are sized so that 99% of wearers can either wear them or need them shortened. Rolex doesn't publish the length. A link isn't cheap, and is non-returnable. If I need a link they can get one in a few weeks.
Really? Not even a dealer knows how long they are?
I tried on a Tudor 41. It fit perfectly.
I saw a Scottish dealer video review of the 41 datejust with an Oyster bracelet. The reviewed put it on. He said he had an 8" wrist and that it fit just right.
An ebay seller of a stainless jubilee bracelet for a 41 said that it would fit up to a 7.5" wrist.
I have tried in vain to find length information on the internet. I'd rather not, after waiting up to a year for the watch, to go to the AD and find I need to order link(s). Is there no one who can lay a similar watch flat with no links removed and put a ruler next to it?
Please?
