Usually for that space you would need between 60k BTU-80k. Depending if the house is newer or used will also play a big difference due to insulation. To be on the safe side i would go between 80k-120k BTU furnace, single stage, upwards horizantal flow is a typical application too. Just be in mind that You should call an HVAC professional to do the sizing . Home Depot might have "professionals" but they aren't as certified as other technicians out there.
