What size is my watch? What size do I need to look for when shopping for a new watch strap? How do I change my strap?

Let’s look into all these questions together …

Watch Strap Sizing Guide

Find out what size you need to look for when shopping for a new watch strap for your Samsung smartwatch. We will guide you through the process of removing and installing watch bands.

You’ll see that changing straps can be done in no time!

The lug size tells you what watch strap width will fit your watch. All Samsung watches are suitable for either 20mm or 22mm watch straps.

Let’s see how to find out the perfect watch strap size for your watch model:

Step 1 – Remove the watchband

Detaching the strap is important before taking the right dimensions.

There are two spring bar systems when it comes to fixing a watch strap to a watch:

  • Standard spring bar system
  • Easy-change spring bar system

Select the right guide depending on the system used in your current watch band:

Standard Spring Bar System:

If you currently own a classic watch strap with a standard spring bar system, follow these steps to carefully take it off.

You will need the following things:

  • A spring bar removal tool
  • A soft cloth or t-shirt
  • A steady hand and some patience

 

Now follow these steps to carefully remove your strap:

  • Place the soft and clean cloth on a flat surface. This protects your watch from getting scratched.
  • Lay the watch face down.
  • Prepare the spring bar tool and locate the spring bar.
  • Gently insert the spring bar tool between the strap and lug.
  • With light pressure, hold the ridge from the spring bar to unhook.
  • Pull the spring bar from the lugs or tilt the watch to release the watchband from the watch case.
Easy-Change Spring Bar System

Most Samsung smartwatches come with easy-to-remove straps. Removing the strap is then much easier:

  • Place a cloth on a flat surface. This protects your watch from getting scratched.
  • Lay the watch face down.
  • Pull the spring bar back using your fingernail.
  • Remove the band from the watch’s body.

And that’s it!

Step 2 – Determine the watch lug size
The lug width of your watch is the space between the two lugs of a watch case. This is where the watch strap is attached to the watch body.

If the size is not indicated, you have two options that you can follow to figure out the lug size:

Option 1 – Use a measuring tool
  • Once you have removed the watchband, prepare a metric ruler or caliper measuring.
  • Measure the space between the inside of the lugs in millimeters.

 

You can measure it in centimeters if mm is not available since the conversion to mm is easier. (1 cm = 10 mm)

Note: Strap Studio’s watch strap length comes in 20cm (8cm + 20cm). All our straps are unisex and will fit most male and female wrist sizes comfortably!

All Strap Studio watch straps fit a lug size of either 20mm or 22mm. These are the sizes that are suitable for all Samsung watches. Choose the watchband under the correct category for the perfect fit. All Galaxy Watch4 and Watch5 models use specially designed and fitted watch straps. You still will be able to use other 20mm watch straps. They will certainly look different!

Step 3 – Measure your wrist size

To make sure our watch straps fit your wrist, we suggest you measure your wrist size. After all, a loose strap would slide up and down your arm while too tight watch straps tend to be uncomfortable when worn for a long time.

Check out these options to determine the right watch strap length:
Option 1 – Download our sizing guide

The easiest way is to download our printable watch size guide and read the instructions to get the right measurements for you! You can then easily check the size of your existing watch strap to make sure our straps will also fit your wrist.

If you have no printer available, you can also do the following:

Option 2 – Use a good-fitting strap you own
  • If you have a strap that fits well, measure the long and short strap lengthwise and separately with a ruler in millimeters.
  • Don’t include the buckle when measuring the strap’s length!
Option 3 – Use a measuring tape
  • Use a tape measure and wrap it around your wrist.
  • Make sure to place it where you usually wear your watch to get the right fit.
  • Determine where the two ends of the tape meet to know the size for you.
Option 4 – Use a thread
  • Get a piece of string and wrap it around your wrist.
  • Place it on the spot where you usually wear your watch.
  • Add a mark on the thread where the two ends meet.
  • Lay the thread flat out then measure the distance from the starting point to your mark on the thread.

Remember: Strap Studio’s watch straps all are 20cm (8cm + 20cm) in length!

Step 4 – Install a new watch strap
Strap Studio’s watch straps are equipped with a “quick release system” for a trouble-free swapping experience.

Follow the guide on the box your strap came in or read through the instructions here:

Attach your new strap

Attaching one of Strap Studio’s watch straps to your watch is so easy, it will only take a few seconds!

  • Prepare the new watch strap.
  • Place the watch case face down.
  • Insert the end of the watch strap’s spring bar into one watch lug.
  • Pull the knob and slide the bar inwards to secure the watch strap.
See? No sweat at all.
Option 4 – Use a thread
  • Get a piece of string and wrap it around your wrist.
  • Place it on the spot where you usually wear your watch.
  • Add a mark on the thread where the two ends meet.
  • Lay the thread flat out then measure the distance from the starting point to your mark on the thread.

Remember: Take the exact dimensions of your watch lug size before changing your watch strap. For example, a 20mm lug size for an easy-change strap will only fit on a watch with a 20mm lug width!
