How to sync contacts between iPad, iPhone and Gmail?

I'd like to have one entry for each person which is the same on my iPhone, and my iPads and Gmail, which I use on my Apple and Windows devices. I found instructions which looked helpful and probably are if you are on the right update level but I must not be. My iPhone is on 18.5.

I should add that I already use iCloud on my Windows devices.

Thanks, Bob

Enable gmail contacts for both of your iphone and ipad.
