I see more and more brush sale postings without knot dimensions.
We all know that knot diameter and loft have a significant impact on the face feel of the brush. And manufacturer specs may have nothing in common with the specific brush on sale.
Is there a way to remind folks - via sticky - in the B/S/T section to include knot dimensions in their postings?
Thanks.

It's a good suggestion.  One of the issues may be that not all members have calipers and can't post the actual knot dimensions.  However, some listings don't even include the manufacturer specs.

A ruler will do. It has mm on it and will provide a good enough approximation.

The ruler and calipers will likely yield different results and will only serve as a way for the buyer to report the brush as not as described. This really opens up a can of worms for the seller.

I don't own calipers, but whenever I advertise a brush, I always state the knot size as:-  00x00 (measured with ruler at opening).

It may not be exact, but definitely no more than 1mm variance in either loft or diameter. I've always considered the true knot diameter to be that at the base and not at the opening, anyway.

If one doesn't have calipers, it's best to list the manufacturer specs.

Any difference is typically under one mm. Take the example of a Simpson brush: it's loft may easily vary by 2-4mm. Way beyond the range of error of caliper vs. ruler.
Below are three Chubby 2s with lofts ranging from 48-54mm and an official spec of 50mm.
I always ask before I buy, but it seems cumbersome to not expect it to be part of the listing.

Dimensions are nearly always expected.  And, I'm with Optometrist.  A  ruler is a decent alternate to calipers.

BTW, Georg, great looking two band Chubby!

Thanks.

Most manufacturers provide a spec, not caliper measurements for each individual brush they sell and people still buy them. Specs are fine IMO, though additional information if available is always nice.

But that (actual) variation can make a difference to me and many others.  I don't care for too many knots smaller than 26mm so if the measurement leans to the smaller side (and they often do), I may not even express interest.
