Front matter · About Grid Maker Pro
Eighty-two grids, one promise — your image stays on your device.
Grid Maker Pro started as a fix for the oldest problem in reference drawing: the grid method works, but drawing the grid by hand steals time from the work.

§ I · Origin
The tool was built for the moment before the drawing starts.
Sarah Chen started Grid Maker Pro while finishing a fine-arts degree, after too many portrait sessions were slowed down by proportion errors and hand-measured grids. The first version had one job: put a clean grid over a reference image without installing software or uploading the reference to a server.
That constraint still guides the project. Grid Maker Pro is designed to be opened, used, and left behind. The output is the working reference; the point is to get back to drawing, painting, layout, or review.
“The grid should disappear into the workflow. If the tool becomes the project, it failed.”
Sarah Chen, founder
§ II · What changed
One grid became a full overlay catalogue.
The early square-grid utility expanded as artists and designers kept running into adjacent needs: portrait construction, perspective, golden ratio, sacred geometry, typography, design templates, and architecture systems.
Today the catalogue covers 82 overlays, but the interface keeps the same premise: pick the guide, fit it to the reference, export the working image.
§ III · The principles
The product decisions are deliberately narrow.
No account gate
The tool needs to work in the moment. Opening it should be faster than finding a plugin, remembering a password, or installing a desktop app.
Overlays are working tools
The catalogue favors systems that solve practical proportion, composition, construction, or review problems.
Education stays close to the tool
Every major overlay gets explanation, use cases, and context so beginners can choose without memorizing art-school vocabulary first.
Intermezzo · Notes from the studio
How working people use it.
For commission portraits the no-upload model is the only reason I can use the tool at all. Reference photos of paying clients don't belong on someone else's server, ever.
I shoot landscape and review three hundred frames a shoot. Bulk overlay mode against Phi, then thirds, then golden spiral — sixty seconds and I know which compositions land.
D&D battle maps printed at 1-inch true scale, taped together, miniatures land in place. Twelve sessions a year for nine years; the grid has never let me down.
§ IV · Founder
Sarah Chen writes the code and the catalogue.
Fine-arts graduate turned developer. Sarah designs the overlay catalogue, writes the educational pages, maintains the tool, and answers the correction inbox. That single editorial line is why the catalogue stays opinionated instead of becoming a pile of unrelated templates.
