Do you insist on using sed? This is easy, for example in python. And no doubt even easier in perl. Though the question is not terribly well defined. Copy a file, removing all lines longer than 2048, or something else?

Here's a solution which deletes lines that has 2049 or more characters:
sed -E '/.2049/d' <file.in >file.out
The expression /.2049/d will match any line that contains at least 2049 characters and deletes them from the input, producing only shorter line on the output.
With awk, printing lines of length 2048 or shorter:
awk 'length <= 2048' <file.in >file.out
Mimicking the sed solution literally with awk:
awk 'length >= 2049 next print ' <file.in >file.out

The above answers do not work for me on Mac OS X 10.9.5.
The following code does work:
sed '/.2048/d'.
Although not asked, but provided for reference, the reverse can be achieved the following code:
sed '/.2048/!d'.

Ah. I installed the GNU version instead of the BSD version that ships with Mac as @Freedom_Ben suggested above. But Kusalananda found the switch to enable extended regex. So you should go with his solution if you still have that problem. ;)

With gnu-sed, you may use the -r flag, to avoid typing the backslashes, and a comma, to define an open interval:
sed -r "/.2049,/d" input.txt > output.txt
with:
- x2049 meaning exactly 2049 xs
- x2049,3072 meaning from 2049 to 3072 xs
- x2049, meaning at least 2049 xs
- x,2049 meaning at most 2049 xs
For the intervals, to not match bigger patterns, you would need line anchors like
sed -r "/^.32,64$/d" input.txt > output.txt

Personally, @Faheem, I prefer your answer. The reason why is that it was very easy for me to turn it around into 'delete all lines smaller than x'. I don't use Python all the time, but when I do I always feel I should learn it well.

The above answers do not work for me on Mac OS X 10.9.5.
The following code does work:
sed '/.2048/d'.
Although not asked, but provided for reference, the reverse can be achieved the following code:
sed '/.2048/!d'.

Ah. I installed the GNU version instead of the BSD version that ships with Mac as @Freedom_Ben suggested above. But Kusalananda found the switch to enable extended regex. So you should go with his solution if you still have that problem. ;)

With gnu-sed, you may use the -r flag, to avoid typing the backslashes, and a comma, to define an open interval:
sed -r "/.2049,/d" input.txt > output.txt
with:
- x2049 meaning exactly 2049 xs
- x2049,3072 meaning from 2049 to 3072 xs
- x2049, meaning at least 2049 xs
- x,2049 meaning at most 2049 xs
For the intervals, to not match bigger patterns, you would need line anchors like
sed -r "/^.32,64$/d" input.txt > output.txt

Do you insist on using sed? This is easy, for example in python. And no doubt even easier in perl. Though the question is not terribly well defined. Copy a file, removing all lines longer than 2048, or something else?
