# Is there a word for numbers between 10 and 99?

I'd like to find such a word instead of saying "greater than 10 but less than 100".

10s? i guess that implies 10,20,30,... – thang Jan 26 '13 at 20:09
Do you mean greater or equal to 10, or strictly greater? – simchona Jan 26 '13 at 20:12
Others have mentioned double digits, but I just wanted to add that in some contexts, this can be shortened to simply double. For example, in basketball, when a player has a "triple double," that typically means he has scored at least 10 points, hauled in at least 10 rebounds, and made at least 10 assists. – J.R.

Assuming you mean 10-99 inclusive, the phrase you want is "two-digit number".

+1 — and the nice thing is, this works for all number bases greater than or equal to 10. ¬_¬ – Robusto Jan 26 '13 at 20:45
@Robusto or less than.. if the context doesn't make the base clear, just write "two-digit [base] number" ("two-digit decimal number", "two-digit binary number", etc..) – Thomas Jan 26 '13 at 23:38
@Thomas: The answer says "10-99"; that leaves out bases below 10. – Robusto Jan 27 '13 at 14:15
@Robusto ... and by the same argument, it also leaves out bases above 10, as 10 is not a two-digit number in base 11. – Thomas Jan 27 '13 at 14:28
Well, yes it is. 10 in base 11 is 11 in decimal. The number 10 in hexadecimal is the number above F, and the number above FF is 100. – Robusto Jan 27 '13 at 14:31

Numbers from 10 to 99 inclusive are often referred to as double figures in the UK.

For example, from yesterday's (British) news:

The death toll during the recent cold snap has hit double figures - as forecasters predicted up to another foot of snow is on the way.

... and is double figures more a UK expression than US? Where we would say double digits or even two digits instead? – GEdgar Jan 26 '13 at 21:19
@GEdgar: Yeah, being in the US I've mostly seen double-digit. Double-figure is a new one to me. – Lynn Jan 26 '13 at 21:21
In the OED, all the examples for double figuress were British, and double digits is marked as originally US. – GEdgar Jan 26 '13 at 21:26
@GEdgar: Good question. Here are the 2-grams: double figures has always been predominantly UK, but double digits has only in the past 40 years or so come to the fore in the US. – Hugo Jan 26 '13 at 21:40
Double figures would be more normal after a verb or preposition, two-digit appositively, in the UK. – Edwin Ashworth Jan 26 '13 at 22:14

There isn't any context in the question, but if the context is something like

The number of people at the meeting was between 10 and 100

then the phrase to use is in double figures:

The number of people at the meeting was in double figures.

Hmm. I seem to have lost 2½ minutes on my answer. I wonder how that happened. – Andrew Leach Jan 26 '13 at 21:10
Sorry to have thereby invalidated your initial comment, but it just seemed daft to leave that inherent conflict between OP's original title and the text of the question. – FumbleFingers Jan 26 '13 at 21:18

Commonly used would be "two digit" or "double digit".

• "Please enter a two digit number"

If you REALLY want to exclude 10 you could say

"Please enter a 2 digit number greater than 10"

-

Not an exact answer, but I find it convenient in common parlance to talk about dozens of things. I hear this used more frequently than 10s when describing a rough quantity. For example:

There were dozens of teenagers at the prom.

It tends to describe > 10 but with a fuzzier upper bound--an upper bound small enough that "hundreds" won't do.
