I think the standard for squeeze bottles are 3cm. That’s what 99% of ketchup bottles I have ever seen are.
Just measured my Kraft squeeze mayo in my fridge and it’s 3cm.
I use my mini spatulas to clean my ketchup containers
Personally I don’t use enough Mayo to run out before I need to replace the bottle. If I got the same size jar it would be the same thing, I’m not scraping out the last bits of months old mayo either way. Doesn’t sound appealing.
In a mmmbop it really is gone
