Art Projector
Turn any tablet or monitor into a tracing projector. Show your reference fullscreen with a grid overlay - free. Pro adds flip, grayscale/invert, brightness, and keep-screen-awake.
A projector that fits in your sketchbook bag
Physical art projectors are bulky and expensive. If you already own a tablet, you have a better one: load your reference, go fullscreen, overlay a grid, and copy it square by square - the same grid method artists have used for centuries, with zero setup. For working on paper from a printed grid instead, use the Photo Grid Maker or Printable Grid.
Two ways to use the projector
Beside the easel (grid copying). Prop the tablet next to your paper or canvas, match the on-screen grid with a penciled grid on your surface, and copy square by square. The screen stays visible while you work at any size - this is the method for drawings larger than your tablet. Use the proportion calculatorto work out your paper's grid spacing.
Under the paper (direct tracing).Lay thin paper over the screen at full brightness and trace the lines that show through - a tablet works like a built-in light box. Lock the screen orientation, turn on keep-awake, and tape the paper's corners lightly so nothing shifts mid-trace. Best for transferring your own sketches, inking, and stencil preparation.
Setup tips that make tracing easier
- Maximize screen brightness and switch the image to grayscale - lines read through paper much better without competing color.
- Use invert for line art. White lines on black show through toned and colored paper where black lines disappear.
- Flip the image horizontally partway through a freehand copy - errors your brain had normalized jump out immediately.
- Dim the image, not the grid, when copying by eye: a faint reference with a clear grid trains measurement instead of outline-chasing.
- Keep-awake matters more than it sounds - a screen that sleeps mid-trace usually means a shifted paper and a misaligned drawing.
Projector tracing vs the grid method
Tracing is fast and exact but teaches little and locks you to your screen's size. The grid method is slower but scales to any surface - up to entire walls with the Mural Scaling Calculator - and every square you copy trains your eye. Professionals use both: trace when the deadline is the point, grid when the drawing is the point. Whichever you choose, check your proportions against the portrait proportion guides before committing to detail.
Frequently asked questions
- How does an on-screen art projector work?
- Instead of projecting light onto paper, the projector mode displays your reference fullscreen with a grid overlay on a tablet or second monitor placed beside your easel. You copy the image square by square using the grid method, or place thin paper over a bright tablet screen to trace directly.
- Can I trace directly from my tablet screen?
- Yes - place thin paper (printer paper or marker paper) over the tablet at full brightness and the image shows through enough to trace. Turn on the Pro keep-awake option so the screen doesn't sleep mid-trace, and use brightness controls to make lines easier to see.
- Why would I flip the reference image?
- Flipping the image horizontally is a classic artist's trick: your brain stops recognizing the subject and starts seeing pure shapes, which exposes proportion mistakes. Many artists also work from a mirrored reference and flip back at the end to check accuracy.
- Is my reference image uploaded to your servers?
- No. The image is loaded directly into your browser and displayed locally. Nothing is uploaded, stored, or transmitted - the same privacy promise as every Grid Maker tool.
- Is tracing art cheating?
- It depends on the goal. For learning observation and proportion, copying square by square with the grid method teaches more than blind tracing. For production work - murals, illustration deadlines, transferring your own sketch to a final surface - artists have used tracing aids from the camera obscura to projectors for centuries. Trace references you have the right to use, and credit photographers where required.
- Should I use the projector or the grid method?
- Use the grid method when you want to build drawing skill or work at a different scale from the screen; use projector-style tracing when speed matters and the output size matches your screen. Many artists combine them: trace the big shapes, then refine details by eye with a grid.
- What tablet works best as an art projector?
- Any tablet with a modern browser works - iPad, Android, or a laptop screen. Bigger and brighter is better for tracing. Set screen brightness to maximum, enable the keep-awake option so it doesn't sleep mid-session, and use a stand or prop it at a comfortable angle next to your easel.
