Home Improvement Questions? Ask a Handyman for Answers
HI my name is ***** ***** I can assist you with your question regarding your downspout size.
Are your 3-inch gutters enough to handle the rains in the area you live? Are they the right size for the pitch and square footage of the roof? plus the amount of rainfall in your area?
The only reason I asked is because 3-inches is not very large, but that could be because I'm used to a lot of rain in this area and you may not have as much rain as what we get here. It all depends on the area you live.
If your gutters are the correct size, than 2" x 3" downspouts should be fine.

How much rainfall do you receive a year?
What is the square footage of the roof of the house?
I thought you said it was a 3-inch gutter. Is this in the U.S.?
I apologize but I have never heard of guttering that small and am not relating to your question. I going to opt out of this session and let another expert help you that knows more about guttering across the U.S. than I do. Thank you, Susan
