simonc - I spent 1 minute and googled “Bianca dimensions”. I then went through the results, until finding something credible, like “lelit.com” - it was the third from the top:

Under technical features, right hand side, to quote:
“Dimensions LxDxH: 29×58.5×39 cm + 8 cm movable tank” (edit: now I read those values I don’t believe it myself! 🤣🤣🤣🤣🤣🤣🤌🤌🤌🤌🤌)
I’m hopping someone who owns a Bianca or has owned one can clarify your query about the power socket/cable. If it has a “kettle lead”, then you can buy one which is angled cowards the left or right, if it helps you sitting the machine better against the wall. I did exactly that with my Elizabeth.
Looking at images here, looks like the power outlet is at the rear just below the tank mount.

Edit 2: some cross checking with a drawing….
Looks like it is, without the tank: 40cm deep, 29cm wide and 40cm tall. So the tank would add approx. 8cm depending where it’s attached to.

Looks like Lelit did a “fat finger typo” and laid out the information rather inconveniently. They keyed in 58.5 instead of 48.5m which would be the depth of the machine including the tank. It would’ve been better if they had typed “Dimensions LxHxD: 29×39×58.5cm incl. 8 cm movable tank”
