Getting tape made to order might come in handy if you want odd sizes. 5 and 8 channel tape is fairly common, but there was also 6 and 7 channel tape (in widths specific to those types) which is far less common. I haven't seen 6 channel tape since the 1970s when it was still used in typesetting equipment, and I never heard of 7 channel tape until recently (it was used on some 1960s era machines).
6 and 7 channel tapes should be the same width, i.e. 22.2 mm. The LGP-30 for example natively uses 7 channel tapes (was also common in the former GDR) but punches only 6 channels.
