Hi Boni,

Archive page will load default blog layout which is blog large Image.
The only way to achieve the blog medium layout for archive page by adding custom CSS Go to Appearance -> Customize/Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save button:

.archive .post-featured-image {
    float: left;
    width: 34.57%;
    margin-right: 4.67%;
}

Thank you!

Regards,
Theme Horse
