Alexa Mini Sensor size - help!

Hi

I was wondering if someone could help me.

I am working with some Alexa Mini footage of 1920 x 2160 resolution and need to determine the correct filmback for this.
Am I right in thinking that I should use the filmback of the native resolution (which I have read would likely be double the width - so 3840 x 2160) which means a filmback of 26.4mm x 14.85 mm (with pixel aspect of 2)?

Any comments/advice would be greatly appreciated.

Will
