HOW TO CHOOSE THE RIGHT SIZE CEILING FAN.

https://www.heating-air-conditioning.org/

In the past, there were pretty much just 3 sizes: 42", 48" and 52" the most popular of which was the 52" fan. Now, manufacturers are making residential ceiling fans that are 60", 72", 84" and even 99" and the most popular size is now 60".

The trend is toward using larger fans in smaller spaces. So in our opinion, most of the ceiling fan size charts you find online are very much outdated.

CEILING FAN SIZE CHART

6' x 6' 3,000 - 4,500 Shop: 24" to 36"

10' x 10' 4,000 - 5,500 Shop: 37" to 48"

12' x 12' 6,200 - 7,500 Shop: 49" to 56"

15' x 15' 7,000 - 9,000 Shop: 60" to 72"

Larger 9,000 - 11,000 Shop: 80" to 99"

I like Patricia's idea of 2 fans. That makes the most sense.

Thanks to everyone for their helpful advise, great insights to consider.

I suppose I should have given more context for the fan. This is is a coastal house in Maine and the room has windows on either side of the room that allow the afternoon breeze to flow through the entire room. The fan is essentially to augment that.

In any case, looks like you pointed me in the right direction. Thanks!

Will you use this room in the winter? Will the fan be used in the winter to de-stratify the heated air?

the fan wont be used often in the winter; its primarily a summer home.

Curious to know what you went with. I’m in the same boat. Any pictures would be great!

Would like to know also what you installed.
