This option is available in the WordPress admin area under the setting/media. Using this feature, you can fix the thumbnail sizes or you can configure WordPress to design a thumbnail image of a specific size – 150×150 images, 300×200 pixel medium image or 600×600 pixel large image.

If you are using an image with a width of 1000 pixels, you can change the settings to large image in the article and select the option to display the full size image – this is one of the most used practices that is followed by the bloggers.
