Ever bought a phone holder only to realise your phone (or chunky case) doesn’t fit, or worse – it rattles around like a tin can on a dirt road? You’re not alone. Whether you’re a tradie bouncing across a job site or a parent shuttling kids to weekend sport, finding the right fitment is crucial for keeping your phone secure, visible, and legal while driving.
Here’s how to measure your phone (with case) correctly, plus tips on choosing the best holder – whether you’re a MagSafe fan or prefer a solid adjustable cradle.
Why it matters: The true dimensions of your phone with its case on are what determine whether it will fit snugly in a cradle-style holder. Too small, and it might slip; too big, and it won’t clip in at all.
What you need:
Your phone in its usual case (thick rugged case? Pop it on!).
A ruler or measuring tape.
How to measure:
Thickness: Place your phone flat on a table with a ruler behind it. Note down the measurement in millimetre
Width: Measure across the widest point of your phone (usually across the screen) with the case on. Again, record in millimetres.
📝 Pro tip: Compare these measurements to the adjustable range listed on product pages like our Qi Wireless Charging Adjustable Holders to confirm a proper fit.
For drivers who want a one-size-fits-most solution, adjustable holders are the go-to. They’re designed with sliding sidearms that lock at your phone’s width, providing a snug grip that doesn’t loosen over time.
✅ Why tradies love them: If you switch between work and personal phones, or plan to upgrade soon, adjustable holders adapt with you – no need to buy a new mount every time.
✅ Easy line of sight access: Adjustable holders can usually rotate 360°, letting you angle your phone perfectly for safe navigation without taking your eyes off the road.
✅ Case compatibility: Holders like ours are designed with extra depth to accommodate thicker cases like OtterBox or LifeProof. No more ripping your case off just to mount your phone!
For iPhone 12 and newer owners, MagSafe mounts are a game-changer. They snap your phone in place magnetically – fast and effortless. But to make the most of MagSafe:
Your phone case must be MagSafe-compatible (with an embedded magnetic ring) or you’ll need to add a slim magnetic plate.
The flatness of your phone’s back is key; chunky wallet cases or pop-out grips can prevent proper magnetic contact.
Our MagSafe Car Mounts deliver a rock-solid magnetic grip tested on bumpy Aussie roads.
Go adjustable cradle if: You use a thick case, switch phones often, or want universal compatibility across iPhones, Samsungs, and everything else.
Go MagSafe or Qi Wireless if: You have an Phone with a Magnetic-compatible case, love the snap-and-go convenience, and want wireless charging in one tidy package.
A phone holder that’s too loose can become a dangerous distraction, while one too tight may damage your case or phone. Taking five minutes to measure your phone + case saves you from that frustration. Pair those measurements with Hold My Phone’s adjustable or MagSafe-compatible holders for a solution that’s legal, secure, and hassle-free.
Remember: it’s about staying safe and keeping your licence. Invest in the best for lasting quality – because when you rely on your phone for navigation or calls, you deserve a holder that fits perfectly and works flawlessly.
