Visual comparison
Compare physical screen proportions and native pixel grids, or switch to CSS viewport references for responsive-layout work. Every drawing uses one shared scale so the relative size remains meaningful.

Proportional comparison of iPad Air 11-inch and iPad Air 13-inch using physical screen dimensions, CSS viewport references, or native pixel grids.
Decision factors
iPad Air 13-inch provides about 45% more normalized viewport area in this reference pair.
Physical pixels help explain screenshot and media detail; live layout still follows the browser viewport and scaling.
iPad Air 13-inch is the larger calculated panel, excluding bezels, curvature, stands, hinges, and chassis.
Practical considerations
Methodology and sources
Physical dimensions are calculated from diagonal and aspect ratio. Named-product hardware claims use manufacturer specifications; CSS viewports remain practical browser references.
How the geometry is calculated
Width and height divide the diagonal using the stated aspect ratio. Screen area is width × height, and PPI divides the diagonal pixel count by the diagonal inches.
Calculated display dimensions, pixel-area differences, and interpretation limits.
Frequently asked questions
Sometimes it can feel close, especially in landscape, but Safari UI, touch input, and scaling still make it a tablet context.
Often yes. Tablet layouts need touch-friendly spacing and should not assume a mouse or large monitor.
Use both 11-inch and 13-inch references if tablet users are important to the product.
