The Samsung Galaxy Watch4 is one of the thinnest Android smartwatches. Nevertheless, the 40mm model still is .46 inch (11.8 mm) deep / thick.

The Samsung Galaxy Watch4 44mm smartwatch is .46 inch (11.8 mm) deep / thick. It is exactly as thin as the 40mm version. Both “classic” models are notably thicker.
Galaxy Watch4: Real-life vs. “official” thickness
The “official” thickness (or thinness) in the specifications provided by Samsung are not consistent:
- 9.7 mm (equivalent to .38 inch) as stated in the official comparison table1
- 9.8 mm (equivalent to .3858 inch, rounds up to .39 inch) as stated in the official specifications2
The official depth measurements exclude the health sensor. My “real life” measurement of the thickness include the sensor. In reality, the smartwatch is .08 inch (2 mm) thicker than stated in the specs, a 20 percent increase.
By the way: the measuring device in the picture is a caliper (also spelled calliper in British English). The secondary smaller scale is called a vernier scale and improves the precision of the reading. Learn more about vernier calipers on Wikipedia or get one on Amazon.
How light is the Samsung Galaxy Watch4?
Using a high precision scale, I measured the weight of the Watch4 40mm and 44mm models. The result were consistent with the official specifications.
The standard strap is made of FKM, a fluorocarbon-based fluoroelastomer material also called fluorine rubber.

Weight of the 44mm “Armor Aluminum” Watch4:
- The 44mm Watch4 weighs 1.07 oz. (30.3 g) without strap
- The 44mm Watch4 weighs 1.88 oz. (53.2 g) with rubber band
How small is the Samsung Galaxy Watch4?
Dimensions of the 40mm Watch4
The 40mm Samsung Galaxy Watch is indeed 40 mm (1.6 in.) wide.

The 40mm model case has a diameter of about 1.58 inches (40.04 mm), which includes the colored strap fixing structure. The black aluminum case inside is slightly smaller and measures about 1.55 inches (39.35 mm) in diameter.
The name of the model (40mm) is factually the size of the smartwatch body and does not refer to the size of the “Super AMOLED” display.
Exact size of the 44mm Watch4 case
The case diameter of the 44mm Samsung Galaxy Watch is 44.5 mm (1.6 in) wide.

The case of the 44mm Watch4 model has a diameter of 1.75 inches (44.50 mm) – this measurement is usually referred as the case size.
Lug to lug distance of the Galaxy Watch4
The lug-to-lug measurement is considered as more important than the case diameter. A watch (or smartwatch) will suit your wrist if its lug to lug distance is 75 to 95 % of your wrist width.

The 40mm Samsung Galaxy Watch4 measures 1.85 inches (46.95 mm) lug to lug. It should suit wrists with a width between 1.95 inches (49.4 mm) and 2.46 inches (62.6 mm).

The lug to lug distance of the 44mm Samsung Galaxy Watch4 is 2.01 inches (51.00 mm). Consider this model if your wrist has a width between 2.11 inches (53.7 mm) and 2.68 inches (69.0 mm).
What is the size of the Galaxy Watch4 display?
40mm Galaxy Watch4 display dimensions
The “Super AMOLED” display of the 40mm Watch4 measures 1.2 inches (30.48 mm), if you refer to the specifications. Placing the caliper on the display, I measured a diameter of 30.45 mm, which converts to 1.1988 inches – pretty close to the official 1.2 inches!
The 1.2 inch display of the 40mm Galaxy Watch4 is surrounded by fairly large bezels.

40mm Galaxy Watch4: Bezel Thickness
The bezel of the 40mm Galaxy Watch4 is impractical to measure precisely. I would say that it is about .13 inch (3.35 mm) wide on each side – definitely larger than on the Apple Watch Series 7.
44mm Galaxy Watch4 display dimensions
The 44mm Galaxy Watch4 shares its 1.4 inch display with the 46mm “classic” version. Note the relatively wide bezel.

Measuring the round display of the 44mm model, I found it has a diameter of 35.45 mm, which converts to 1,3957 inches. However, it is quite difficult to measure precisely without better instruments. I assume that the display must be exactly 1.4 inches wide, as stated in the specifications.
Is the Galaxy Watch4 a good smartwatch for women?
Admitting that there is such thing, the answer is yes: the Samsung Galaxy Watch4 is definitely one of the best smartwatches for women. The “Pink Gold” variant obviously targets women.

The “Silver”-colored model, which is almost white, can also be seen as an excellent smartwatch for women. The black Galaxy Watch4 has a unisex positioning and targets both men and women.
Which Samsung smartwatch size fits my wrist size?
Depending your wrist size, here is a table to help you find the right Samsung smartwatch size.
Without measuring your wrist
| Wrist size (circumference) | Watch4 model |
|---|---|
| Very small under 14 cm | 5.5 in. | – |
| Small to medium 14 – 17 cm | 5.5 – 7.1 in. | 40mm |
| Standard 18 – 21 cm | 7.1 – 8.3 in. | 40mm or 44mm |
| Large 21 – 23 cm | 8.3 – 9.1 in. | 44mm |
| Extra large 23 cm | 9.1 in. and more | 44mm (or 46mm classic) |
3 thoughts on “How to change the default application for a type of file on Linux”
I have .wma audio files showing as text files. It doesn’t help to use “open with” a media player because Mint thinks they’re text docs so nothing happens. Weirdly, one song in one folder IS still an audio file – and plays fine. Is there a global way to wipe out file associations and then re-associate via terminal?
In my Debian Jessie system, the per user settings are at: $HOME/.config/mimeapps.list
