Fitbit Charge 4 Bands Australia: Styles & Sizing Guide
Quick answer: The Fitbit Charge 4 uses a slide-in band attachment shared across the Charge 3 & Charge 4 range, available in two sizes — Small (fits 140mm–180mm wrists) and Large (fits 180mm–220mm wrists). Any band in our Fitbit Charge 4 Bands collection clicks straight onto your tracker in seconds, no tools required. Below you'll find every style we stock in Australia, how to pick the right size, and how to swap your band at home.
What Bands Fit the Fitbit Charge 4?
The Fitbit Charge 4 accepts any band built for the Charge 3 & Charge 4 fitting. Both trackers use an identical latch-and-slide connector, which is why every band in our range is engineered to suit the pair. That gives Charge 4 owners access to the full spectrum of styles — classic silicone, breathable sports straps, stainless steel Milanese mesh, genuine leather, metal link bands, and limited-edition printed designs.
What doesn't fit matters just as much. Bands made for the Fitbit Charge 5, Charge 6, or Charge 2 use completely different attachment systems and will not connect to a Charge 4. If you're not certain which Charge model you own, jump to the FAQ section at the bottom of this guide before ordering.
How Do I Choose the Right Band Size for My Charge 4?
Fitbit Charge 4 bands come in two sizes. Measure your wrist circumference with a soft tape measure (or a strip of paper marked and laid against a ruler) at the point where you normally wear your tracker:
| Band Size | Wrist Circumference | In Inches | Best For |
|---|---|---|---|
| Small | 140mm – 180mm | 5.5" – 7.1" | Slimmer wrists; most women and teens |
| Large | 180mm – 220mm | 7.1" – 8.7" | Broader wrists; most men |
If you measure right on the 180mm boundary, consider how you like your tracker to sit. A snug fit improves heart-rate accuracy during workouts, so borderline measurements usually do better in Small — but if you prefer a relaxed, breathable fit for all-day wear, size up to Large. Note that our Milanese magnetic bands and stainless bangle styles adjust across a wide range, making them forgiving choices if you're between sizes.

Our Most Popular Picks
If you simply want a fresh version of the band your Charge 4 came with, the Classic Replacement Straps are the straightforward choice and come in a wide colour range. Fitness-focused wearers gravitate to the AirVent Sports Strap for its breathability, while the Milanese Magnetic Lock remains our best-seller for anyone who wants their tracker to look at home in the office.
For something distinctly yours, the Inkdly special edition range brings printed designs you won't find anywhere else — including Gliterry Spring, Floral Harvest, Purple Plaids, Leopard Safari, Blazing Camouflage and Sugar Skulls.
How Do I Change the Band on a Fitbit Charge 4?
Swapping a Charge 4 band takes under a minute and needs no tools:
- Remove the old band: Flip your tracker over. On the underside where each band section meets the tracker body, you'll see a small flat button (latch). Press it down and slide the band away from the tracker. Repeat on the other side.
- Attach the new band: Line up the new band's connector with the slot on the tracker, then slide it in until you hear and feel a click. Repeat for the second half.
- Check it's secure: Give each side a gentle tug. A properly seated band won't shift or wobble.
If a band feels stiff on first insertion, that's normal — the latch is designed to grip firmly so your tracker stays put during exercise.
Complete Your Charge 4 Setup
While you're refreshing your band, two accessories are worth adding to protect and power your tracker:
- Slimfit Protective Case & Screen Protector — a slim TPU bumper that wraps the tracker body and shields the display from knocks and scratches without adding bulk.
- Replacement Charger Cable — keep a spare at work or in your travel bag so a forgotten cable never means a flat tracker.
- Refuel Charger Stand — an alloy dock that gives your Charge 4 a dedicated home on your bedside table or desk while it charges.

Fitbit Charge 4 Band FAQs
How do I know if my Fitbit is a Charge 4?
The Charge 4 was released in 2020 and looks very similar to the Charge 3, so checking is worth 30 seconds. The definitive method: open the Fitbit app, tap your device icon, and the model name appears at the top. On the tracker itself, the Charge 4 has built-in GPS — if your tracker shows a GPS exercise mode that works without your phone nearby, it's a Charge 4. You can also check the model number printed on the back of the tracker body or on the original box: the Charge 4 is model FB417.
What's the difference between Charge 4 and Charge 3 bands?
The Charge 3 and Charge 4 share the same band attachment system, which is why the bands in this collection are designed for both models. If you own either tracker, everything in our Charge 4 collection will fit. Charge 3 owners can also browse the dedicated Fitbit Charge 3 Bands collection.
Will Charge 4 bands fit a Fitbit Charge 5 or Charge 6?
No. The Charge 5 and Charge 6 use a completely different band attachment that is not compatible with Charge 4 bands. If you've upgraded, head to our dedicated Fitbit Charge 5 Bands or Fitbit Charge 6 Bands collections for bands built for those models.
Will Charge 4 bands fit a Fitbit Charge 2 or Charge HR?
No. The Charge 2 uses its own press-fit connector and the Charge HR has a fixed, non-removable band design. Charge 2 owners should shop the Fitbit Charge 2 collection, and Charge HR owners can find accessories in the Fitbit Charge HR collection.
Is there a Charge 4 Special Edition, and do these bands fit it?
Yes. The Charge 4 Special Edition is the same tracker with a different bundled band, so every band in this collection fits it identically to the standard Charge 4.
Which band is best for workouts?
The AirVent Sports Strap is the workout favourite — its perforations let air circulate so sweat dries quickly and skin stays comfortable through long sessions. The Sports Loop is another strong option if you prefer a soft fabric feel with fine-tuned adjustability.
How long does delivery take within Australia?
Orders placed on business days are dispatched the same day from our Melbourne warehouse. Delivery times then depend on your location and the shipping option you select at checkout — full details are on our shipping page.
