Can you automatically calibrate Xbox screen size to tv screen size

If you mean adjust overscan, this is a function of your display. Please consult your manual whether that is possible on your model.

I have gone through the calibration, I can get the xbox to work fine and it will fit the screen ok. But when I switch to TV mode it is small picture and I have to reset the picture size on the TV and it is over scanned. Then if I go back to the xbox I
have to reset the picture size.

You most likely need to adjust the screen size, which can be done by going to your Xbox's Settings > General > TV & Display options > Calibrate TV. Press Next until you get to the Aspect Ratio & Sharpness screen. At that screen, go to your TV's settings and change the aspect ratio.

Unfortunately, the Xbox One and Series X|S consoles do not have a built-in feature to manually adjust the screen size. The console relies on the TV's settings to adjust the screen size, so if your TV does not have the option to adjust screen size, you will not be able to adjust it on the console.

However, there is a workaround for this issue. You can try using the "Overscan" setting on your TV. Overscan is a feature that allows you to adjust the size of the image being displayed on your screen. This will help you to adjust the screen size to fit the edges of your TV.

The steps to adjust overscan may vary depending on your TV, but you can usually find it in the TV's menu under "Picture" or "Display" settings. Once you have found the overscan option, you can adjust the size of the image being displayed on your screen.

It's worth noting that the feature is not available on all televisions and brands, it's a TV specific feature, you may want to check your TV's manual or consult the manufacturer's website for more information on how to access and use this feature.

Another option is to use a third-party device such as a scaler, which can adjust the resolution and aspect ratio of the video signal being sent to your TV. These devices can be connected between the Xbox and the TV, and can provide more flexibility in adjusting the screen size.

Likely a setting on your TV that adjusts screen size is the problem.

On your TV, bring up the settings menu with the TV remote, and find the setting that adjusts aspect ratio or screen size. You are probably set to “zoom”.
