Which Size Sells?

This question is what prompts pixel people the world over to pause, to upgrade, to worry endlessly.
I wondered, but not long. Over the past several months I’ve been coaxing information from three general sources about sales. These sources are more the low volume direct to collector/buyer sale.

Sources Of Information

The sources have been
galleries — 4 in three different cities.

I assume that they serve different, maybe even, very different client types, with different tastes and aesthetics.

online paper sales companies — 2

Their sales probably overlap although not much. Most buyers, like me, likely stick to one supplier and await ‘specials’ provided the regulars.

frame sales from —

1 online vendor, and a chain sales shop. I was given information from two different stores in the chain about the size frame they sold in bulk to single users. I asked this question believing that this person was framing for sales rather than for their own personal use.

Another Answer

During the course of this, I was told by one of the gallery owners that she noted that if the buyer purchased a large print (larger than 24″) she did not see the buyer as frequently as the person buying the smaller prints. In fact in her contact data base she marked the person differently than she marked “collectors” making a first purchase. Every gallery kept track of collectors and treated them differently than purchasers. This goes so far in one case that the gallery provides a smart-phone app for collectors.
