Greater Than > or Plus +

I want to convey a requirement that has a minimum but no maximum to my users. For instance 8.

Which is more understandable? Participants: >8 or Participants: 8+ ?

From layouts point of view >8 is more favorable because it can be right aligned along with other numbers too.

• If you want to get technical, they each have different meanings anyway. >8 = greater than 8 8+ = greater than or equal to 8 Commented Nov 1, 2011 at 5:16
• It depends on the context. In the wrong context 'participants 8+' could be read as those who are over 8 years old. Commented Nov 1, 2011 at 10:29

• @Knu technically correct but UTF-8/ect extended characters are generally good to avoid. Commented Nov 1, 2011 at 17:26
• I believe that the "8+" form is very particular to the engilsh language. So take that into account if you're doing something that will be translated into multiple languages. Commented Aug 6, 2012 at 15:31

Possibly neither, they each have different meanings:

>8 = greater than 8
8+ = greater than or equal to 8

• Uh, ok, so then how about `>7` vs. `8+`? Commented Nov 1, 2011 at 19:23
• 8+ is more intuitive to me at a glance. >7 would be used in a mathematical context, but in a UI, I would use 8+ myself. Commented Nov 1, 2011 at 21:51

Definitely `8+`. I've met college graduates who still get the less than and greater than signs mixed up.

• What about +8 ? Commented Nov 1, 2011 at 3:46
• @MoeSweet - I don't think so. You never really see the `+` before the number with this kind of thing. If right-aligning is such an issue, couldn't you just pad the numbers that don't have a `+` with a single space? Commented Nov 1, 2011 at 3:54
• I would interpret +8 as a stupid way to write 8 (in contrast to -8). Commented Nov 1, 2011 at 7:25
• If you're dealing with a gamer, +8 means you add 8 to an object or action (I have a cloak with +8 dexterity). 8+ would mean you have to achieve something of at least 8 (you need to roll 8+ in order to kill the dragon). So there's some more...esoteric logic behind the differences. Commented Nov 1, 2011 at 16:35

You'll find enough people who will not understand `8+` (basically everybody who works outside of IT). But everybody who attended a school should understand `>7`.

Could you not write it in English? "More than 8" "8 or greater" "8 or more"?

• Doesn't have space for that. Thanks anyway. Commented Nov 2, 2011 at 2:05

We had this discussion internally and went for 8+. It seems to make most sense to most people. >8 refers to math while you are more likely to come across 8+ when for example checking the pricing table at Disneyland.

• Agreed. `<` and `>` are used in programming, mathematics, etc. But they aren't seen and used in every day life for most people. Commented Nov 2, 2011 at 20:34

@PhillipW made a good point. It depends the context. With 8+ you may have double meaning, while >8 is a safer choice.

"min. 8" or "8 min.". This is of course longer than what you have proposed but it is more verbose and has less of a change of being misunderstood.

8+” might be ambiguous as it could be interpreted as “more than 8.”

I’d use “≥8.”
