When evaluating the Ring Doorbell 2 for your home security setup, one of the most critical physical specifications to confirm is the Ring Doorbell 2 width. Proper measurement ensures a seamless installation without the need for additional drilling or, worse, purchasing an incompatible device. This dimension is essential for DIY enthusiasts and professional installers alike, as it dictates compatibility with your existing door frame and hardware.
The Ring Doorbell 2 represents a significant upgrade from the original, featuring improved motion detection and a sharper camera feed. However, its physical design requires careful consideration. Understanding the exact width helps you determine if it will fit securely into your door, especially if you have narrow frames or are replacing an older, bulkier model. Getting this measurement right the first time saves you time, frustration, and potential restocking fees.
Ring Video Doorbell 2 Physical Dimensions
The Ring Doorbell 2 dimensions are standardized across the device to ensure a consistent fit for most standard door installations. The specific width of the Ring Video Doorbell 2 is 5.2 inches (132 mm). This measurement is taken horizontally across the widest part of the device, typically from the edge of the mounting plate on one side to the opposite edge.

To provide a complete picture of the hardware you are installing, the height of the Ring Doorbell 2 is 2.65 inches (67 mm), and the total thickness is 1.25 inches (32 mm). These dimensions are crucial not only for the initial fit but also for understanding the depth required within your door’s pre-drilled holes to accommodate the unit and its wiring comfortably.
Compatibility with Standard Door Frames
One of the reasons the Ring Doorbell 2 remains a popular choice is its adherence to standard US door hardware specifications. The standard width of an interior door in the United States is typically 1 3/4 inches (4.4 cm), but the passage for the door handle usually measures 2 1/8 inches (5.4 cm) wide. The Ring Doorbell 2 width of 5.2 inches is designed to bridge this gap comfortably.
- The device is significantly wider than a standard door handle hole.
- This ensures the unit sits flush against the door surface, providing a clean and professional aesthetic.
- It fits perfectly within the space where a peephole and deadbolt assembly are usually located.
Installation Considerations for Narrow Frames
While 5.2 inches fits most modern homes, older properties or specific custom installations might present challenges. If your door frame is particularly narrow or the area around the handle is trimmed with dense woodwork, you must measure the available space before ordering.

You need to ensure that the horizontal space from the edge of the striker plate on the door frame to the edge of the door itself is greater than 5.2 inches. This prevents the device from protruding awkwardly or catching on the frame when the door closes.
Mounting Hardware and Spacer Issues
The included mounting bracket for the Ring Doorbell 2 is designed to match the device’s width precisely. However, issues can arise if you are replacing a larger, legacy doorbell system. Older systems sometimes have larger junction boxes or wiring configurations that stick out.
If the existing hardware or wiring protrudes into the 5.2-inch width constraint, the Ring Doorbell 2 may not sit flat against the wall. In such cases, utilizing the extension spacer kit included in the box is essential. This spacer slides behind the doorbell, providing the necessary depth to adjust for the obstruction and ensuring the width does not compromise the flush mount.

Visual Comparison and User Perspective
To put the Ring Doorbell 2 width into perspective, imagine a standard smartphone. Most modern smartphones, like an iPhone or Galaxy series, have a width of roughly 3 inches. The Ring Doorbell 2 is nearly twice as wide as your phone, making it a substantial but not overwhelming presence on your door.
This size allows for a bright, visible status ring and a wide-angle camera lens without making the device obtrusive. It is large enough to be noticeable as a security deterrent but compact enough to blend in with most residential architecture.
Summary of Key Specifications
For quick reference, the following table summarizes the critical linear measurements of the Ring Doorbell 2, with the width being the primary value for installation planning.
| Specification | Measurement | Metric Equivalent |
|---|---|---|
| Width (Horizontal) | 5.2 inches | 132 mm |
| Height (Vertical) | 2.65 inches | 67 mm |
| Depth (Thickness) | 1.25 inches | 32 mm |
By adhering to these dimensions, Ring ensures that the Ring Doorbell 2 maintains a universal fit for the majority of customers, simplifying the upgrade process for security-conscious individuals.
