Tbf, sometimes the measurements are iffy. I bought a 55 inch TV that fits comfortably on my TV table. The TV had some issues so I went through a return with the manufacturer and they didn’t have my specific TV in my size so they offered a 65 inch. I asked them if the measurements for the stand were the same and they read off the same distance as the 55 inch. I thought great! It will fit.
TV arrives and the stand legs were just an inch short on either side of the table, definitely not the same! But it still fit. I ended up securing the TV with those child straps just in case and plan to replace the table eventually.
Can’t wall mount at the moment because of spacing issues but eventually will.
I had a similar issue with a monitor, the stand leg distance was listed but not the fact that it’s width is half my desk. It doesn’t help that some stores and manufacturers don’t have a standardized list either.
