Thanks bud. Glad to be a part of the collaboration!
I'm adding to the post above. Just now I went outside with tape measure in hand. The Yakima System on the Chevy Bolt and I carefully measured and thought of multiple configurations.
It appears the Chevy Bolt EV roof square inches is: 65 Inches Long (from the windshield to the back) x 38 Inches Wide (between the Chevy Bolt EV Premier side rails).
From this maximum area, we potentially reduce down the size due to weight restrictions of the Chevy Bolt EV roof.
Earlier today I spoke with a Senior Product Specialist on all these configurations, and many roof systems. Just because your roof has ample space, does not mean you can simply freely go with that maximum size. He advised us to avoid his mistake when he was still young and inexperienced. He was going on a weekend trip and went with a large Cargo Box due to the ampile available roof space. His mistake was also over packing beyond the recommended weight capacity of his car. After the trip, the 4 roof rack towers (that connect the Car to the Crossbars) made 4 dents in his car roof.
He said that you will see these roof rack systems are rated for a maximum weight capacity. However, it is most important to also contact GM / Chevrolet to find out the recommended weight allowance for the Chevy Bolt EV roof. We need to take into account the weight of our cargo, plus the weight of the roof system itself.
What is the weight allowance of the Chevy Bolt EV roof?! Does anyone here know? I have seen multiple answers. It appears that 165 pounds is the general rule of thumb?!

So coming full circle with this information...,
we are at 65 Inches Long x 38 Inches Wide,...
and reduce our measurement from here.
The length measurement includes the back hatch door fully opened to simulate its functionality while on a trip with a potential Cargo Box $$$$ / Cargo Basket $$ / Cargo Bag $. The great news is, it appears GM / Chevrolet designed a well made hatch. The hatch door never passes further than its hinge. Meaning the angle of the hatch hinge and the door itself stays at 90 degrees or less. In other words good for us as the hatch door does not protrude into the useable area that a Cargo Box / Basket / Bag would occupy.
In saying that, note the back Antenna Fin. The good news is the Antenna appears to be short enough in height for the clearance of any Cargo Box / Basket / Basket with a Bag, that will all rest on top of a Roof Rack Crossbar system you choose. In choosing the Box / Basket length, potentially the length could be right up to the back hatch door. The Antenna should not interfere. However it should also be noted that the Antenna Fin will interfere with a Cargo Bag that would rest directly on top of the car roof. In this case if you were to use a Cargo Bag, you will need to be 12 inches less in length to give room for the Antenna Fin.
By the way, that same Senior Rep had another great tip. If you need to save money on a budget, just go with the Cargo Bag. Now one of two things with the Cargo Bag. A large bag will rest on top the Crossbars. A smaller bag may be able to fit between the 2 Crossbars. Either way, please use "Moving Blankets" between the car roof and the Cargo Bag. Fold the blankets as needed. U-Haul has them for purchase, or perhaps Home Depot / Lowe's. Fold the blankets as needed. The car roof is protected from scratches, and the Cargo Bag is supported with a flat surface from underneath (especially if the Cargo Bag rests on the Crossbars).
For me, the max size for me is around 57 Inches Long x 38 Inches Wide. Give or take a few Inches either way. Again, mindful of the weight.
However, just talking about the width for a moment. Standing on the open car door frame to access the roof adjustments, 38 Inches seems awful wide to work around and keep your balance? Perhaps something more narrow?
Looking at Luggage size is also important. It appears an XL suitcase measures 32 Inches Long (High) x 29 Inches Wide. Laying the Luggage length along the car roof length seems to make the most sense?! This way the Luggage 29 Inches Wide matches up with the car roof width also. You agree?

For us, the Cargo Box pro is awesome as it is rigid and the most aerodynamic.
However the cons are the boxes are extremely expensive!?!? Even more expensive than Pelican Boxes?! Four Dollar Signs $$$$. Why do companies charge $1,000 for Large Boxes, to perhaps $400 for a small one?! There should be a dancing girl inside or super bowl tickets with the box, or a dancing girl with super bowl tickets!
The other challenge for us is the storage. The box being rigid is a pro while en route, but a con while in storage for the remaining 90% of the time.
Perhaps the Cargo Bag is a better choice for us. The pro is just one dollar sign $. Ebay has them for as little as $25 to $75. Many in the $55 range.
cargo bag | eBay. Or OverStock.com or CraigsList.org.
The other pro is the storage. A Bag can be folded up and take little room.
The con is it is a bag. LOL. Less aerodynamic (some are better than others). It may rip? The manufacturers claim the bags are weather / rain proof. What about security? Perhaps a luggage lock?
However for our Chevy Bolt EV Premier, the side rails are flush with the car. Fastening the Cargo Bag straps down at multiple points is important to us. But we dislike the bag designs where the straps enter and exit through the car door windows, thus penetrating into the cabin of the car; that looks tacky, amateurish, and as if it was an afterthought. Plus back seat passengers entering and exiting the vehicle becomes a challenge.
So we are thinking go with the Cargo Basket with a Cargo Bag inside. The Basket will support the Bag.

Applying all this reasoning is fine as long as the manufacturers have the sizes we need.
The Yakima 4 Cargo Baskets.
Roof Baskets
yakima.com
Of these the only two sizes that seem reasonable for us are either the:
SkinnyWarrior at a whopping 58 Inches Long x 23 Inches Wide.
(Too Long)
The SkinnyWarrior, cargo basket is perfect addition for your next adventure. Load up your duffels, coolers, camp gear and even mount bike rack to it!
yakima.com
or the LoadWarrior at 44 Inches Long x 39 Inches Wide.
(Too Wide)
The LoadWarrior, cargo basket is perfect addition for your next adventure. Load up your duffels, coolers, camp gear and even mount bike rack to it!
yakima.com
Perhaps Goldie Locks will find the right size from a different manufacturer?! LOL.
Again I think Yakima is very good.
However the prices for even Baskets is too high.
Checking eBay...
