Tutto Machine On Wheels

Will the tutto 20" fit my juki hzl-f300 w/dimensions: 17.5 width, 11.4 height, 8.2 depth, weighs 21 lbs! just want to be sure to buy correct size.

Does the height dimension include the wheels?

What is the diameter of the wheels (approx)? Trying to be sure it will fit in my tiny space.

Does anyone have the viking ruby royale? does this fit? mine measures one inch higher on height...wondering if there is any flexibility at the top?
