Number of bars/measures per line

[pdxdjazz]

: is there a way to fit more than 4 chords in a measure? ?

This issue is readability. Even using the small font, four complex chords in four adjacent spaces are too crowded to read easily. As you figured out, you can make the measure longer, (even using a whole 16-space line).

I suppose you could enter the changes the using "text" instead of "chords". They'd be small, but you could read them sequentially under the measure in question before moving on.

Another option for 8 chords in a 4-space measure would be to write the first four as "alternate" chords, above the second four "standard" chords.

Here's an example of both:

irealbook is a great tool. But like all tools, it has some design limitations.
