Horizontal same width menu items

Hello
Is there a way to make any horizontal menu item the same as the longest item or just all the same width please?
For vertical menu's I have worked out how to make them all look a standard width as they sit on top of each other and this looks really nice and neat
But for me Horizontal menu's I have noticed that the width seems to be dependent on the word used for the menu item.
For example as a vertical menu I can set all the items to be the same width if they read like this and I like how standardised that looks

Some Really Long Title For A Menu Item
Small

But as a Horizontal setting the same menu items would have a small width for 'Home' and 'Small' and a longer width for the 'Some Really Long Title For A Menu Item'

I wouldn't have one that long of course but just to show what I mean.
Hope I am making sense and if it is possible

Thank you

Hi
this is the normal behavior, having a fixed / same size for the items is not that good, but possible using custom CSS
