For me 6' is too narrow. We had a 6' deck and added 8' more to it. The cost isn't that much more and you'll love your outdoor room. Trust me, I'm so glad we made it wider.

6x15 will probably feel a bit like a coffin :) at least that's my feeling in long, narrow spaces. I'd go a bit wider if you can -- even 8' will feel better although I'd probably go 10'. It's cheaper and easier to do it now than later! Have fun building and enjoying your new place!

Our porch is 6 x 15, and it's not coffin-like at all! I might have liked another foot deeper, but it works for us. We have 2 chairs and a love seat, a coffee table and side table. Lots of houseplants summer on the porch. Great spot to watch the birds at the feeder. (If I could only figure out how to post a picture, I would!) Small house, couldn't acccommodate a larger porch, but we enjoy it. I love the fact that the mosquitos can't get me!

Our old house had a 4' deep porch, and we used to sit sideways. Personally, in parts of the country that have good 'porch weather', the bigger the better.

I'd suggest you go deeper also - at least to 8 feet. With 15 feet in length, you will be able to have a sitting area and room for a small table and chairs for eating, laptop/desk work, hobby/crafts, etc. without feeling cramped.

We have a screened in porch that is 10x10 and can fit 6 adults nicely...

I'd recommend 8-10 feet to be comfortable.

On my big house I have a screen porch that is 7'wide by about 15'. For the 2 of us, or even with a 3d, it is fine. We have a small table against one long wall with 3 chairs, a double glider thing with end table between the seats (great for reading)at one end of the porch and I usually have a small 3drawer chest for garden stuff at the other end.

I think it depends on how you expect to use the space. If you plan to entertain groups of people frequently, you would want something bigger. If it's just 2-3 people relaxing or having breakfast-you should be ok with 8x15. I do think you'll like 8 ft better than 6.

A screen porch is one of the nicest "extras" you can add to a house ,imho. Lot's of pleasure for relatively few bucks.

I agree with everyone else ... I had a deck built on the back of my house ... I had the measurerments so small ( trying to be frugal ) My BIL looked at the plans and said -it looks good on paper - but when it's built - you'll be sorry you made it that small. He was right. He made it bigger & I'm happy he did . Things on paper sure look different in real life.
