The size is broken into width and height.

Check the "Maintain aspect ratio" box.

By doing so, you can change the value of the width, and Paint.NET will automatically calculate the correct value for the height (or vice versa) so the photo won't get distorted.

Enter a smaller width.

If you don't want to do pixels, you can choose a different measurement from the drop-down menu.

Adjust the height and click "OK."

Since the aspect ratio is maintained, the height will adjust automatically. If it's too tall, you can adjust the height manually—the width will update automatically so the photo isn't warped.
- Don't be afraid to experiment! Paint.NET has a nice undo function that will quickly restore your photo to its original size (plus, you have that backup copy).

If you lower the quality, the file size will be smaller. If you don't care about file size at all, just leave the slider at 95% or 100%.
