I actually calculated this out with proper math for my monstergirl world. The fun part if you know some geology is that Earth is actually way denser than it should be. We've got about two normal inner planetary cores worth of iron and nickel due to the protoplanet that hit us and made the moon back when. It's the reason we're right on the teetering edge of a gravity well that barely lets us launch stuff into space with modern rocketry. So that let me make a much bigger world with a more standard composition.

Fun part is even as big as I made it, the world has only about 4/5 the gravity at sea level. And without a single giant moon, you got less drag on the world over the eons so it can still spin fast enough for a relatively normal day.

Argana metrics:

Gravity on the surface of Arga at sea level G=8.02 m/s^2 (81.75% Earth gravity)
Mass is 1.49x10^25kg (roughly twice that of earth)
Diameter roughly 10,000km (roughly 1.5 that of earth)
Surface area 1.3 x10^10km (over two times the surface area of Earth)

2 Moons (tidal-locked)

Day (23.2 hours)


So there's a reason why the Argan girls call Earth a small hard world. For them, the altered horizon angle is disorienting, and they feel heavy and sluggish. And for Terrans going the other way, the air feels thin and the change in rotational speed causes something akin to sea sickness until they can get used to it.
