Paper is the ultimate wireframing tool for building quick concept mockups and prototypes, with full creative freedom.
We use the oversized version of this kit throughout our digital psychology training, where we apply behavioral science to interactive design, UX, and marketing — across websites, apps, wearables, and conversational AI agents.

Because our focus is on creative concepts rather than pixel-perfect specs, the kit provides practical ballpark dimensions across a wide range of popular devices and formats.
Our grid is based on a widely-used full-width web layout: 1,200 pixels wide, divided into 12 columns of 100 pixels each, with a 10-pixel sub-grid shown in both light and dark gridlines. This structure lets you divide your layout into thirds, quarters, or sixths — covering the vast majority of real-world design scenarios across devices.
Device proportions follow the common sizing conventions of popular products from Apple, Google, and Microsoft.
Ad templates are sized to match the most common formats used across major search engines and social media remarketing platforms.
