I found how to widen my blog over at the Letter 4. The link to their tutorial is here. It is very, very helpful! I used it to make my blog wider, and I am loving the amount of space! The problem I had was figuring out the width that I should crop my blog title to, since the right side did not match up with my "pages" section. I cropped many different sizes and finally came up with one that fit perfectly! I want to share how I did it!
I started out with this image, that I made in Photoshop Elements. I haven't used online photo software much, but I bet it would be easy to figure out on their programs.
My blog size is currently 1300 px wide. The size I cropped this to that turned out perfectly is 1220 px X 275 px. I am so happy with how it turned out! Depending on your blog's width, you may have to try out a variety of sizes until you get what you like. I cropped, saved, cropped, saved, etc.
I am no pro with this kind of thing, but I would be happy to try to answer any questions, or help you find the correct size! I do know how to do that!
