How to Change Blogger Blog Width

To adjust the width size of your blog according to your preference, you can do so at the HTML section:

Dashboard > Layout > Edit HTML
Then you can change the width size to the size that you prefer.


#header-wrapper {
width: 750px;
}

#outer-wrapper {
width: 750px;
}

#main-wrapper {
width: 490px;
}

#sidebar-wrapper {
width: 230px;
}


Header-wrapper and outer-wrapper determines the maximum width of your blog.

Main-wrapper determines the width of your blog content and sidebar-wrapper determines the width of your sidebar.

Make sure that the total pixel (px) allocation for the main-wrapper and sidebar-wrapper is not more than the outer-wrapper's size.
