Choosing the Right LCD Screen Size
for Your Project
When it comes to LCDs, size isn’t just a design choice and it’s a functional one. Whether you’re building a compact sensor or a full-sized industrial interface, choosing the right display size impacts usability, performance, and overall experience.
At 4D LCD, we offer display sizes ranging from as small as 0.96” all the way up to 21.5”, with the option to fully customise dimensions, aspect ratios, cutouts, and interface types to suit your exact project requirements.
So how do you decide what size you need?
Start with how your product is used
If your device is handheld or wearable, like a health tracker, smart tag, or compact control unit, smaller screens from 0.96″ to 2.8″ are ideal. They’re light, efficient, and easy to integrate in tight spaces.For interfaces requiring user interaction, like smart home panels, industrial controls, or embedded HMIs, the mid-range sizes between 3.5” and 10.1” give enough space for clarity and touch-friendly design.
If you’re working on kiosks, digital signage, or complex dashboards, a larger display (15.0”–21.5”) provides the visual real estate needed for graphs, multiple inputs, or data-heavy screens.
