What should I consider when choosing business cards printing?

[businesscard]

I was looking into business cards for a small business project and wanted to understand what makes a printed card look professional without making the design too crowded. There are different options for paper thickness, finishes, sizes, and layouts, so I wanted to compare them before placing an order.

While going through some printing resources, I found this page about business cards printing. It helped me understand the available printing options and some of the details worth checking before preparing a design.
