How important is circular needle length?

If my pattern calls for a 29" length circular needle but the closest size I have is 32" will it work for the pattern?

If you’re knitting something flat like an afghan, should be just fine! If it’s for something in the round, it will depend on how many stitches you’ve cast on, otherwise they might be a bit stretched out.

Or to put it another way, if you’re knitting something larger than 32" around, you’re fine. If it’s smaller than 32", you may easily run into trouble.

Ok, I understand now. Thanks ladies! :smiley:
