🎨 Mobile Design Tips
Less space doesn’t mean less impact. Here’s what to keep in mind when designing for mobile:
Keep text short & sweet
Small screen = small real estate. Avoid overcrowding and focus on a single, clear message.
Use high-quality images
Crisp visuals matter more than ever on mobile. Make sure your images and graphics are high-resolution so your brand looks its best – even on a tiny screen.
Mind your font sizes
Make sure your text is legible without zooming in. A good rule of thumb: bigger than you think.
