Dexcom G7 Sticker vs. Dexcom G6 Patch: What’s the Difference?
The Dexcom G7 and G6 are continuous glucose monitoring (CGM) devices that help manage diabetes, but they differ in design, size, and features. Here's a quick breakdown:
- Dexcom G7: Smaller, all-in-one sensor and transmitter, 30-minute warm-up, 12-hour grace period, worn on the back of the upper arm (ages 2+).
- Dexcom G6: Larger, separate sensor and transmitter, 2-hour warm-up, no grace period, worn on the abdomen or upper buttocks (ages 2-17).
Quick Comparison
| Feature | Dexcom G7 | Dexcom G6 |
|---|---|---|
| Device Design | All-in-one unit | Separate components |
| Size | 1.07" x 0.94" | 1.2" x 1.8" |
| Warm-up Period | 30 minutes | 2 hours |
| Grace Period | 12-hour replacement | None |
| Wear Location | Back of upper arm, etc. | Abdomen, upper buttocks |
Both devices offer customization options like stickers and patches for added style and functionality. The G7's smaller size makes it more discreet, while the G6 has a proven track record for durability. Choose based on your preferences for size, wear location, and setup simplicity.
Look and Style
Measurements and Fit
The size and shape of the device play a key role in designing stickers and patches. The G7 needs stickers tailored to its smaller, compact dimensions, while the G6 requires patches designed for its larger, more elongated sensor. These differences impact adhesive coverage and how the patches wear over time.
| Feature | Dexcom G7 Sticker | Dexcom G6 Patch |
|---|---|---|
| Device Size | 1.07" x 0.94" | 1.2" x 1.8" |
| Shape | Compact, rounded | Rectangular, elongated |
| Sensor Design | All-in-one unit | Separate components |
| Insertion Style | Perpendicular | Angled |
Design Options
There are plenty of third-party options for customizing these devices. Pump Peelz offers waterproof, skin-friendly adhesives with prices ranging from $4.00 to $34.99. Their designs include seasonal themes and custom options. For those looking for something entirely personalized, Pump Peelz specializes in fully custom designs.
Personal Design Choices
If you want a completely unique G7 sticker, Pump Peelz lets you create custom designs. Beyond aesthetics, the G7's perpendicular insertion design reduces the risk of compression-related false readings, an improvement over the G6's angled insertion. These features combine practicality with personal expression, giving users a chance to make their devices truly their own.
How They Work
Stick Time and Strength
The G7 sticker and G6 patch both rely on medical-grade acrylic adhesives to stay in place for up to 10 days. The G7 uses a modified adhesive formula that matches the G6 in terms of staying power. Proper application is key to ensuring they work as intended:
| Application Step | G7 Sticker | G6 Patch |
|---|---|---|
| Site Prep | Apply to a flat, hairless area | Apply to a flat, hairless area |
| Initial Care | Allow a 12-hour dry period | Allow a 12-hour dry period |
| Grace Period | 12 additional hours after 10 days | No grace period |
| Adhesive Type | Modified acrylic-based | Standard acrylic-based |
These adhesives play a big role in ensuring durability, especially when it comes to handling moisture and maintaining sensor accuracy.
Moisture Protection
The Dexcom G6 patch can handle being submerged in water up to 8 feet deep for 24 hours. For added durability, third-party options like Pump Peelz G6 patches provide water resistance and sweat protection for up to 10 days or more.
To keep your sensor secure, dry the area thoroughly after water exposure, trim any loose edges, and use medical tape if needed for extra reinforcement.
Sensor Performance
Accurate readings are essential. Here's how sensor placement impacts performance, based on recent data:
| Placement | MARD (Mean Absolute Relative Difference) | Agreement within 20% |
|---|---|---|
| Arm | 8.2% | 95.3% |
| Abdomen | 9.1% | 93.2% |
Both sensors are designed to resist common interferences, but the G7's smaller size and faster 27-minute warm-up time give it an edge. This accuracy, combined with its compact design, ensures it performs well while also offering a sleeker look.
Comfort While Wearing
Material Safety
Dexcom G7 stickers and G6 patches use medical-grade acrylic adhesives that are latex-free and designed for up to 10 days of wear. These adhesives undergo strict irritation testing to ensure safety for most users. The G7 features a slightly updated adhesive formula compared to the G6.
For those looking for alternative adhesive options, third-party brands provide specialized solutions.
Movement and Fit
The adhesives are designed to flex naturally with your body, keeping the sensor securely in place even during movement. Pump Peelz offers customizable adhesive patches that combine reliable adhesion with skin comfort, ensuring they stay put during active use.
Skin Reactions
Although hypoallergenic materials are used, some users may still experience skin sensitivity. Research has identified 2,2'-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate (MBPA) as a possible allergen in the G6 adhesive. To reduce the risk of skin reactions, consider these tips:
- Rotate sensor sites with each application.
- Allow your skin to rest between uses.
- Avoid applying moisturizer on the day you place the sensor.
- Follow proper site preparation instructions.
"If you have significant skin irritation (itching, burning, and/or rashes at the site of the adhesive patch), contact your healthcare provider and report it to Dexcom via the Product Support Request Form".
Some users have reported itching after three days of wear and irritation when using the patch for the full 10 days.

Comparison of Dexcom G7 and G6
The Dexcom G7 and G6 each bring their own advantages to the table. The G7 stands out with its smaller size, quicker warm-up time, and an all-in-one applicator that makes setup simpler and more convenient.
When it comes to performance, there are some key differences. Pump Peelz offers specialized G7 patches designed for extended wear.
In terms of reliability, the Dexcom G6 tends to perform better, offering stronger adhesion and fewer sensor issues. If you're using a Tandem pump, it's essential to confirm that the G7 is compatible before making the switch.
Customization options are available for both models, with basic designs starting at $4.00. For those with sensitive skin, hypoallergenic patches are also an option.
Here’s how to decide:
- Go for the G7 if you want a smaller device with an integrated sensor and transmitter design.
- Stick with the G6 if you value better adhesion and a proven track record for sensor reliability.
Whichever you choose, both models offer options for personalization without compromising on functionality or accuracy.
