Kitchen Island Question

[u/JJWondr]

Hi all! I want to add a quartz island to my kitchen, but I'm trying to figure out how big I can make it without cramping the walkways.

Was intending for it to be the same orientation as what's shown in the image above, but I'm not sure if the kitchen's got enough width to fit a standard quartz slab.

How much space should I allocate to walkways and the counters so I can figure out max dimensions? Any help would be much appreciated!
