Duct Label too small

[bari.ewing]

I'm know this has probably been answered, but I can't find it. In my model and paper spaces my duct size labels are teeny tiny, barely able to see. Both my annotation scale and viewport scales are set to 1/4"=1'0". I must be missing a step. I have one drawing were it seems to work fine, but not in this one. Any help would be appreciated? It should be noted that this file was orginally created in a much older version of CAD. I'm not sure if that is the problem. Thanks!

I think you should check the text styles used by both drawings and make sure they match. Although we don't do mechanical here, we made sure the labels use an annotative text style.
