If you’re shopping sleeves or hard shells for AirPods Pro 3, the exact case dimensions matter — a few millimeters can decide whether a lid shuts cleanly or a speaker cutout lines up. Here are the official measurements and how they stack up to recent models.

AirPods Pro 3 case: the exact size and weight

The MagSafe Charging Case (USB‑C) for AirPods Pro 3 measures and weighs as follows:

  • Height: 1.86 inches (47.2 mm)
  • Width: 2.45 inches (62.2 mm)
  • Depth: 0.86 inch (21.8 mm)
  • Weight: 1.55 ounces (43.99 grams)

The case supports MagSafe, Apple Watch, and Qi wireless charging, and charges via USB‑C. It also includes a built‑in speaker and lanyard loop and carries an IP57 dust, sweat, and water resistance rating alongside the earbuds.

How it compares to AirPods Pro 2

Apple’s current compare page lists the AirPods Pro 2 case at 1.78 x 2.39 x 0.85 inches and 1.79 ounces. In other words, AirPods Pro 3’s case is slightly taller and wider, a hair deeper, and notably lighter.

Model Height Width Depth Weight
Pro 3 1.86 in ⬆️ 2.45 in ⬆️ 0.86 in ⬆️ 1.55 oz ⬇️
Pro 2 1.78 in 2.39 in 0.85 in 1.79 oz
  • Height: +0.08 in (Pro 3 vs. Pro 2)
  • Width: +0.06 in
  • Depth: +0.01 in
  • Weight: −0.24 oz (lighter)

Why it matters: rigid snap‑on shells molded for Pro 2 often rely on tight tolerances. The Pro 3’s slightly larger footprint can keep the lid from closing cleanly or cause misalignment with the case’s speaker and lanyard cutouts, even though both generations include those features.

How it compares to AirPods (3rd generation)

The non‑Pro AirPods (3rd generation) case is smaller and narrower at 1.83 x 2.14 x 0.84 inches and 1.34 ounces, as listed in the official support article. That’s a substantial width difference versus Pro 3.

Model Height Width Depth Weight
Pro 3 1.86 in ⬆️ 2.45 in ⬆️⬆️ 0.86 in ⬆️ 1.55 oz ⬆️
AirPods 3 1.83 in 2.14 in 0.84 in 1.34 oz
  • Width gap (Pro 3 vs. AirPods 3): +0.31 in
  • Height/depth: small differences, still non‑trivial

Translation: sleeves or shells built for AirPods 3 won’t properly fit the Pro 3 case (and vice versa). The shapes and interior lid geometry also differ.

Will your existing case or sleeve fit?

  • AirPods Pro 2 → Pro 3: Expect tight or incompatible fits with hard shells due to the Pro 3’s slightly larger dimensions. Flexible silicone sleeves might stretch, but alignment for the speaker, lanyard loop, and charging port can still be off by a few millimeters.
  • AirPods 3 → Pro 3: Dimensions and geometry differ too much for reuse.
From → To Result Notes
Pro 2 → Pro 3 ⚠️ Tight / Misaligned Hard shells may not close; silicone sleeves might stretch but cutouts off.
AirPods 3 → Pro 3 ❌ Not Compatible Too different in size + geometry.

Tip: If you’re measuring an existing sleeve, target internal dimensions of at least 47.2 mm (H) × 62.2 mm (W) × 21.8 mm (D) to avoid compression. For cutouts, the Pro 3 case includes a speaker and lanyard loop; check that accessory designs account for both.

Other notes

  • Charging options: The Pro 3 case works with MagSafe, Apple Watch chargers, Qi‑certified pads, and USB‑C.
  • Ingress protection: The IP57 rating applies to both the earbuds and the case. Don’t charge when wet.
  • Weight differences: Despite being slightly larger, the Pro 3 case is lighter than the Pro 2 case, which can change the feel with heavier shells attached.

Bottom line: If you want a sure fit, look for accessories specifically labeled for “AirPods Pro 3” and verify their listed dimensions. Small changes in height and width make cross‑generation reuse hit‑or‑miss, especially with hard shells.
