I'm trying to picture how big a 3-4 pound chihuahua is, can you help?

So she would be about 1/3 of the size of a cat? Like a gfruit? A cantaloupe? Could fit in my hand? I'm trying to give an example to my landlord. I haven't adopted her yet because I can't until I have permission. I have just seen her on line. Does anyone have any life size photos that would really help or any help please? Thank you very much! :)
