Grid Maker Docs ｜ Create Precise Drawing Grids in Your Browser

Learn how to use Grid Maker to upload images, overlay customizable grids, and download print-ready references in seconds.

Overview

Grid Maker is a browser-based tool that lets you upload an image, overlay a customizable grid, and export a reference file for drawing, sketching, or planning layouts. Everything runs online—no install—so you can stay focused on proportions and composition instead of measuring by hand.

Core Capabilities

Upload & overlay: JPG/PNG/WebP up to 15MB, drag-and-drop or file picker. Nothing leaves your browser.
Grid controls: Set rows/columns, adjust line color, opacity, and width, toggle labels (A1, B2…).
Paper formats: A2/A3/A4/A5, Letter, Legal, or custom sizes (mm).
Preview & filters: Live canvas preview with optional black-and-white conversion.
Printing guide: Auto-calculate line counts and intervals for the chosen paper size.
Export: Download your grid overlay as a high-resolution image for print or on-screen reference.

Quick Start

Open Grid Maker and click Upload Image (or drag a file).
Set Rows and Columns; choose Line Color, Opacity, Width, and Show Labels.
Pick a Paper Format (or enter custom width/height in mm).
Preview, optionally convert to Black & White, then Download Grid Image.
Use the Printing Guide to draw matching lines on paper or confirm spacing for digital work.

Detailed Settings

Grid Type: Custom or Square; align to rows/columns ratio when using square mode.
Labels: Turn on/off cell labels (A1…); great for teaching and step-by-step transfers.
Appearance: Fine-tune line visibility with color, opacity, and stroke width to keep guides subtle.
Paper Format: Quickly switch among common sizes; custom mode supports exact dimensions in mm.

Printing Guide (Auto)

For the selected paper size, Grid Maker shows:

Vertical lines count and interval; horizontal lines count and interval.
Label range (e.g., A1 to D4) when labels are enabled.
Use these values to reproduce the grid on physical media or verify digital spacing.

Tips for Best Results

Choose a grid density that matches your drawing scale—fewer cells for loose sketches, more for detail.
Keep line opacity low for on-canvas drawing; raise opacity when printing.
Use square mode to maintain consistent proportions across devices or print sizes.
Re-download after changing paper size or line settings to keep guides accurate.
