ᐅ Is a driveway paved with 40x20x8 mm pavers suitable?

Hello,
we are currently choosing paving stones for our driveway.
There will be two areas:
9 x 5 meters (30 x 16.5 feet)
6 x 3.20 meters (20 x 10.5 feet)

We have selected:
Kann Multitec Color Nero bianco in the size 40 x 20 x 8 cm (16 x 8 x 3 inches)

In the new development area, we noticed that almost everyone uses smaller pavers. I haven’t seen the size 40 x 20 cm (16 x 8 inches) anywhere else.
Does the larger size we chose have any major disadvantages?
Do the large slabs look odd on our driveway?

Thanks for your opinions!

No, they are more expensive and possibly also costlier to install. I am not familiar with the price thresholds for exterior work related to higher labor costs or effort. That might be why homeowners who have already spent their last penny cannot spend more than necessary.

We probably won’t know until you have them installed and share a photo of the entire area here.

I believe I have heard that larger paving stones might be more likely to crack under heavy point loads (e.g., a car) compared to smaller stones. I would check on this in advance.

According to the manufacturer, the stones of this size are approved for passenger cars and occasional delivery traffic.

Are there then any disadvantages regarding long-term settlement or similar issues? Or does that depend more on the substructure?

We installed 40cm by 20cm (16 inches by 8 inches) paving stones. This size is quite common in our residential area. Laying them was not a big issue. Larger stones (although I don't find 40cm by 20cm that large) eventually become too cumbersome to lay by hand. With smaller stones, however, you face other challenges, especially regarding the evenness of the surface. Our neighbor used stones around 7cm by 7cm (3 inches by 3 inches), installed by a landscaping contractor, but the result doesn’t look particularly uniform.

A 40x20 (cm) (16x8 inches) profile is used in every other house here. Totally common and nothing special. No issues when installing it.
