How do you measure square feet? I have to measure my house for insurance purposes?

ask: "How do you measure square feet? I have to measure my house for insurance purposes?"

Last year it was insured for 1600 sq ft. This year they decided (on their own wihtout measuring it) that it is 3,000 sq ft! Even the town taxes me at 1400 sq ft! The insurance company said the town does that to help ppl save on taxes but I'm not so sure I believe them. This town is money hungry. Its not like them to try to help someone. Unless they can help you part with your money. My house is 1&1/2 story. The upstairs walls are slanted inwards in all rooms but one and the short hallway. It is a 4 bedroom but very small rooms. The insurance company said to times length by width and then add 1/2 of that for the upstairs. Is that right? I'm not sure I believe them. All they want is my money!
