UK "standard" chess board size. Whaaaat!!!?

I just read (here) that the standard size for chess board squares in the US is 2" to 2.5" which is what I expected. But it also says "...in the UK the standard size chess board is approx 3.75 inches (95mm) per square. So your pieces should have a 2.3 - 2.8 inch base.".

It's in a section about tournament boards, so I expected big, but 3.75 inches? No way! I don't recall ever seeing pieces that big either.

Surely some mistake. I guess they meant 2.75" but calculated base size from the erroneous figure. Right?

I was actually trying to get an idea of the most commonly used size BELOW 2" in the UK (or anywhere really), but struggled to find a consensus. Essentially, a normal smaller board size for non-tournament play. Any ideas? Informed guesses welcome too. Thanks.

Has to be a typo...those pieces would be MASSIVE. Also, if it was the "standard" size in the U.K. then they would be fairly common over there, right?

I agree. For my understanding 3.75 inch is the size of the king. Perhaps a typo. 😎

They removed the whole paragraph referring to the UK standard. The quote in my OP was cut and pasted from that page.

It was just a typo that has been quickly corrected. No biggie. Old screenshot with uncorrected typo below to show OP is not going crazy... yet. 

I played tournaments with a 2.75" board and 4.25" pieces in the 80's.  These a very broad based pieces.  I don't know when they changed the size of the boards to 2.5 and 2.25.

As for a library set.  1.5" squares and a 2.75 inch King with a 1.5" base is what I use.  it has been my most used set.  A very old wooden Staunton set that has held up well.
