What size button for base of triple pleat?

[suel]

What size cover button do most of you use for the base of pleats. I normally use 19mm but this job has a fairly bulky fabric, I was not sure if to use the next size up to be sure the fabric would squeeze into the button. These will be full length curtains and 5" deep pleats - will 23mm be too big?

Thanks,
Sue.

The button size I use is 22mm so 23mm would be fine.
