Which would you use: full-size, full-sized, full size or full sized?

I want to use full-sized, as in:

Click here to download a full-sized version of this image.

But Google NGrams disagrees:

"Full size" wins overwhelmingly, with "full sized" marginally above zero.

So, given:

  1. full-size
  2. full-sized
  3. full size
  4. full sized

which would you employ and why?


Solution 1:

From Collins Cobuild English Dictionary:

full-size or full-sized A full-size or full-sized model or picture is the same size as the thing or person that it represents.

So, I would choose one of those options and trust the dictionary.

Solution 2:

I really couldn't decide between full-sized and full-size in your example: both would be perfectly fine and common. Note that you need the hyphen in either case, because it is a compound adjective (an adjective composed of more than one word) and it comes before the noun it belongs to. If you put it after, you don't need the hyphen: this picture is not full size. (Note that it is often more stylistically pleasing to use a different construction in that case.)

Solution 3:

Either option is correct and usable. Both they have slightly different emphases. "Full-size" indicates that it is of the right size, while "full-sized" may additionally imply that it was deliberately made to that size. It's a very slight difference.

@Cerberus is correct that no hyphen is used when you put it afterwards.
