Large Font Data Cards

I'm trying to create Google Analytics style dashboards using our own internal data. I'm having difficulty creating data cards like the ones found in the image I've attached. Notice the font in the single data point cards and how big it is. If you've tried to create data cards in PowerBI desktop or the service, you'll notice the max font size is 40 and even when you choose to resize the cards on your dashboard after you've published and pinned, the font shrinks along with the card size. There ends up being a lot of empty/dead space surrounding your data point. Ideally, the number would take up the entirety of the card. I'm at a loss for what to do. Is this not something we can do with Power BI? Can only big names like Google and others who have public facing content packs utilize these larger fonts? Any help or insight will be appreciated. Maybe I'm missing something, but I've searched for how to do this and I've come up empty.
