I am writing software involving sequences. At various points, I want to specify that some operation involves or produces a sequence as long as a given sequence.

If its length was lower, we would say "shorter". If the length was higher, we would say "longer". But what adjective do we have for the length being equal that isn't "equal-length" or "same-length"? Because hyphens are not allowed in identifiers in software, I would like a single word with the same meaning. For example, I have a countShorterSequences and countLongerSequences defined, but countEqualSequences is not correct and countEqualLengthSequences is confusing considering my sequences contain lengths of other objects, making them "length sequences".

There is only one similar thread on the same topic, but it is not about comparatives (shorter vs. longer) but positives (short vs. long) with the in-between being "medium". That's not what I want.

Equidistant comes to mind, but that means equally apart rather than equally long.
