The four rules that keep pricing coherent as your work moves between studio, gallery, and website.
Square inch
(Width × Height) × your rate, plus materials. The industry-standard method for 2D work: it scales cleanly across sizes and keeps a body of work consistent.
Emerging artists typically land at $1–3 per square inch; rates climb with exhibitions, sales history, and reputation.
Linear inch
(Width + Height) × a linear rate, plus materials. Because dimensions are added instead of multiplied, small works don't come out absurdly cheap and large works don't balloon. Useful if you work across many formats.
Hourly + materials
(Hours × hourly rate) + materials. Guarantees you're paid for your time, which makes it a good floor, especially early on. But price the finished work, not the struggle: two same-size pieces from one body of work should carry the same price even if one took 10× longer.
Gallery commission
Galleries typically take 40–60% of the retail price, most often 50% for 2D work. Your formula result is your take-home, so the wall price must be grossed up. And it must be the same everywhere. Undercutting your gallery from your own website is the fastest way to end the relationship.
Consistency wins
Whatever number you land on: hold it. Same-size works from the same body of work get the same price. Raise prices in small, confident steps as work sells. Steady, defensible pricing is what builds collector trust.
