Drawing Grid Maker: GridValue

Art Photos Reference Tool App

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

GridValue turns any photo into a drawing guide. Add a grid to your reference, match it on paper or canvas, and draw square by square. HOW IT WORKS • Choose a photo or try the built-in sample. • Pick your paper or canvas size and a grid such as 6 × 8. GridValue shows the exact size of every square in cm or inches. • Zoom into one square at a time, lock the view, and draw without losing your place. • Export a print-ready guide as PDF, PNG or JPG and see the printed cell sizes before you print. MADE FOR DRAWING • Coordinate labels (A–F, 1–8) so you always know which square you are on. • Grayscale mode to judge values without colour distraction. • Adjustable line colour and opacity that stay thin at any zoom. • Projects save automatically, so you can pick up where you left off. GRIDVALUE PRO • High-resolution 300 DPI exports without a watermark. • Unlimited saved projects. • Print at the right size: A4, A3 or Letter with true cell measurements. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple ID account. Manage or cancel anytime in Settings.
