Height of header image

Is there a way to change the height of the allowance for the header image on the Frontpage? The image I am using is getting cut off where I don't want it to, and the only way to have it show correctly is to downsize the browser window, but I'd like the effect of the browser window being fullscreen and the image not being cut off.

Hello,

You can change header (image) height in Theme Customizer settings, please go to Appearance -> Customize and "Images" Section, here you can configure height of your frontpage images (depends on device, image may have different height)

Nice!!!!
