The Math (Don't Panic!)
Let's say you've got a gorgeous photo that's 1600 × 1200 pixels, but uh oh, your blog can only fit 400 pixels wide. What now? Time for some aspect ratio wizardry! ✨

(original height / original width) × new width = new height
(1200 / 1600) × 400 = 300

Boom! Your resized photo is 400 × 300 pixels and looks perfect. No squishing, just pure proportional beauty.
