I agree with silent - in this world the map size is fine - the environment is stunning a huge open world isn’t required & this is only early access who really knows how large it gets
.
If they open up the entire sword coast instead of just the forgotten realms area....oml. I run a campaign on Roll20 in the sword coast, and I set it to scale. (I did this by getting distance measurements between two cities on a to scale HD map that was posted on I THINK DnD Beyond if I'm not mistaken. I then kept adjusting my distances per hex until the distance between two cities matched up with the scale measurement on the map I found). Top to bottom is almost 1700 miles. This may be off give or take a couple hundred miles, but that is roughly the length of the entire map of the sword coast.
For scale, to travel from Baldur's Gate, as the crow flies, you will basically be traversing parallelle to the Chinthar River. It is about 210 miles between these two cities. And Candlekeep, which is South of Baldur's Gate, is about 175 miles away. That's the closest city marked on the map I have of the Sword Coast.
Huge distances here. Not so bad by horseback but on foot? yeah.
