Or try another measurement. On my monitor:
- the 77H and 77G both have roughly 32mm cabin width, so I assume the maps are of the same scale
- first cabin and business cabin have same cabin width
- two rows on business is about 12mm length on my monitor
- two rows of first is about 20 mm

So (including aisle space)
- each J seat is roughly 48 sq mm
- each F seat is roughly 106.67 sq mm, 222% of J (122% more)

Where did you get your 50% from?
