Our packet is at approx 300 pages so far, with copies of letters, invoices, phone bill records, pictures of us together at family functions and trips, etc... so how much is enough? Is there such a thing as too much of a good thing? We don't want to leave out important stuff, but where do we draw the line? If 10 pictures of some activity, like our wedding, is good, is 100 better?
Generally, one picture of each event or occasion is enough, except for the big things like the wedding, honeymoon, and engagement party, or the equivalents. For the actual marriage ceremony, you want shots of everything your culture would consider important - so an Indian couple had better have photos of all the key ceremonies. For the reception, you should have photos that document the number of guests you had: either one shot of everybody, or maybe several shots - perhaps the couple posing with each table of guests, for example. You would not believe how often the visa officers question the number of guests at the wedding. However, you still do not need lots of photos of essentially the same thing, even for the wedding.
Some visa officers have complained that people send in too much, but I have never heard of anyone being refused for too much proof. I have heard of people being denied for not sending in enough.
It depends on the visa office and your relationship. Someone applying from the first world needs less evidence on average than someone from the third world. A relationship that has no red flags needs less evidence than one where there are a lot of red flags.
One good point is to get as many different types of evidence as possible: 1,000 pages of texts is not as good as a selection of texts, emails, phone bills, proof of joint accounts, and a few letters from family.
For things like emails, texts, and maybe phone bills, you do not have to send in proof of every one. A selection of emails and texts from the beginning, middle, and present time of your relationship will be enough. You can then add the logs showing how often you sent emails, and state that you can send more if the visa officer wants them. Because the average land-line phone bill will just be a page, I would send all of those.
