Picking a design is the fun part of getting a custom phone case — but “fun” can turn into “overwhelming” fast once you’re staring at a blank template. Here are proven design directions that actually look good in person, not just on a screen, organized so you can find your phone model and start designing in minutes.

Make Sure You’ve Got the Right Fit First

Before picking a design, confirm your exact model — a case built for the wrong phone will misalign the camera cutout and button openings. GTTG custom cases currently support:

iPhone and Galaxy phone model compatibility for GTTG custom cases

If you want a magnetic / MagSafe case, remember that option is iPhone-only for now — Galaxy owners get the same materials and protection in the non-magnetic versions. For a full rundown of materials and protection levels, see our complete buyer’s guide.

1. Your Own Photo

The single most popular design choice, and for good reason — a favorite travel photo, a picture of your dog, or a candid shot of your kids turns a case into something nobody else has. For the sharpest print, use a photo that’s at least 1000×1000 pixels; anything smaller can look soft once it’s sized up to cover the case.

2. Minimalist Monogram

If a full photo feels like too much, a clean initial or short monogram on a solid background reads as understated and a little more “professional” — a good pick if your phone doubles as a work device.

3. Matching Couple Cases

A single image split across two cases so it completes when both phones sit back-to-back is a genuinely fun idea for partners, best friends, or siblings. It photographs well too, which makes it a popular gift request around anniversaries and Valentine’s Day.

4. Travel and Memory Collages

Instead of one photo, some of the best-looking cases use a simple 2–4 photo collage — a trip, a wedding, a first year with a new pet. Keep it to a few images so each one is still recognizable at case size.

5. Team Colors and Fan Design

If you’d rather rep your favorite team than a personal photo, GTTG also offers fan-inspired NFL, NBA, and MLB-style case designs — a simple way to match the team gear already in your closet. (These are original fan-inspired artwork, not officially licensed team merchandise.)

6. Bold Text, Quotes, or Lyrics

No photo? No problem. A short meaningful quote, a favorite lyric line, or even just your name in bold typography can look just as striking as a photo — and it’s an easy option if you’d rather keep things simple.

A Quick Tip Before You Design

Whatever direction you choose, keep the top corners and camera area in mind — that’s where the case cutout sits, so avoid placing text or a face right at the very edge. Centering your subject in the middle 80% of the image keeps it safe from any cutout across every supported model.

Once you’ve got a direction, building the case takes about two minutes: choose your case type, select your exact phone model, then upload your design.
