To get the overall size in square inches, multiply the painting's width by its length. Then multiply that figure by a predetermined cash sum suited for your reputation. For oil paintings, I now charge $6 per square inch. Then, calculate the cost of canvas and framing and double it by two. That's your price.
Now you can sell your work! There are several ways to go about this: at an outdoor market such as Santa Monica's Pacific Coast Highway; in a gallery (see 'What is a gallery?' below); or on your own website. You may want to start small by selling only a few pieces a month so you don't empty your wallet too fast!
If you decide to sell through a gallery, be sure to find one that suits your needs. For example, if you want feedback on your work before it's sold, look for a small cooperative where everyone knows each other. If you need to ship your piece home after it's been accepted for sale, ask if the gallery has a policy on this issue. In general, look for a friendly atmosphere where people help each other promote their work. It's also helpful if there are a few similar artists represented by the gallery, so you have someone to talk to about topics such as marketing, pricing, and publicizing shows.
Finally, you need to give some thought to how you will describe your work.
To get your square inch pricing, multiply the length by the breadth of your artwork. An 8 by 8 inch piece, for example, is 8 × 8 = 64 square inches. If you charge $1 per square inch, this would be $64 plus the cost of supplies if you include them. Most professionals estimate that it takes about 20 minutes to an hour to paint a square foot, so you could easily earn $160-$320 for an acrylic painting.
If you use a standard color palette (the colors you choose to use in your painting), it's easy to calculate how much your painting will cost. Just start with the price of pure white oil or acrylic paint and add amounts of red, blue, yellow, and black to create different tones. For example, one can make a dark gray by mixing black and charcoal at a ratio of 4:1; one can make a light gray by using white and charcoal at a ratio of 1:4. There are many other combinations for various shades of gray, but these two examples should give you an idea of how to begin calculating prices.
Once you have calculated the price of your painting, you need to consider factors such as quality, quantity, and salesmanship. Are you willing to spend the time required to produce a high-quality work? If not, then why should someone else? Also, how much work does a painting like this take? A lot!
Professional interior painting will most likely cost between $1.50 and $3.50 per square foot. When the ceiling and trim are factored in, the cost rises to $3 to $4 per square foot. These figures do not include the time it takes to paint or the expense of hiring a professional painter.
Interior painting costs vary based on several factors such as the type of material used for the surface, the quality of the paint used, any special preparations needed for the walls or ceilings, etc. Generally speaking, though, you can expect to spend anywhere from $150 to $300 or more for a single-story house with average size rooms. For a larger home or one with many stories, the price will be higher.
Painting an interior room is much different than painting a exterior wall. You will need to take into account the texture, color, and materials used inside the room that may not appear important outside. However, the main difference between an exterior and interior room is the amount of damage that could occur to the room if not done properly. An exterior wall can be easily painted over while an interior room may have furniture placed directly against it when drywall is put up. This means the paint has to be able to cover any defects in the wall surface without peeling or flaking off later.
