This is one of those simple, yet overlooked settings in WordPress. With as many dashboards as I have visited, I always see these numbers set to the default.
So what am I talking about?
Every time you insert an image into a post or page, you have four options when choosing the size.
But did you know you can change these?
First, let me point out something. I often get asked why on occasion is one of these sizes not available to choose. For example, the “large” size in the screenshot above. The reason for this is that the file you uploaded is smaller than the large size is set to. WordPress never lets you bump up the size here. Which is a good thing. That will most likely result in a fuzzy, unclear photo.
Now back to the settings. Select settings > media.
At the top of the window you will find these options. This is where “thumbnail”, “medium” and “large” can be edited.
Now to answer the question: Why would you change these? There could be all sorts of reasons. You might want to enlarge or reduce the default thumbnail size if they show up on your blog page. Or maybe you want a specific size all the time for certain images to make it consistent. Again, this would do the trick. Give some thought to the media settings and decide how they can best help you.

Great quick tip! I’m giving you the big blue bird!
I’d also add that I like to use the Regenerate Thumbnails plugin (http://wordpress.org/extend/plugins/regenerate-thumbnails/) after I add/change media sizes.

You can also add more custom sizes to the defaults in your child themes functions.php file
Thanks, that is a great tip for anyone comfortable with php. As you probably guess from my blog, my readership is more on the user end that doesn’t want to or deal with php, they would rather have the simple non-code fix.

Simply copy and paste the code from the StudioPress code snippets into your child themes functions.php file. No need to write or edit any code.
Or there’s also a plugin which does the same thing Bob!

Yeah, it sounds simple, but even pasting code into a file can be intimidating for some. And then the issue is if they want to remove it they will never remember what they did. And if they aren’t using a StudioPress child theme, will, thats another issue, as it could get overwritten with an update.
It actually drives me nuts when devs say just copy and paste this code in. I have had dozens of people who were told to do that come to me months later, wanting to remove the code and its functionality and for the life of them cannot. They end up spending time googling it or hiring someone to do that. It can be very frustrating for them.
Plugin is good, and often a better option if the only other choice to be adding code snippetns. But if you can do it this way, why add another plugin
