18mm vs 20mm Chain: Find Your Perfect Fit Fast!

When it comes to finding the perfect chain, I’ve learned that the width plays a crucial role in determining the overall look and feel of your jewelry. Through my experience, I’ve discovered that the choice between an 18mm vs 20mm chain can make a significant difference in the overall look and feel of your jewelry.

I’m excited to share my insights with you, helping you find the ideal chain width that complements your personal style and elevates your accessories game. Let’s embark on this journey together and discover the perfect chain for you!

Understanding Chain Width

Chain width is the thickness of the chain links. It’s measured in millimeters. An 18mm chain is a bit thinner than a 20mm chain. But both are considered to be on the larger side of jewelry chains.

The width you choose will affect how your necklace looks, feels, and can be worn.

Visual Impact and Style

18mm Chains

  • Have a more understated and refined look
  • Work well with many outfit styles, from casual to formal
  • Are good for a range of pendant sizes, giving better balance and proportionality

20mm Chains

  • Make a bolder statement with their larger width
  • Create a more eye-catching and dominant look
  • Are great for those who want their jewelry to stand out
  • Pair well with larger, bolder pendants or can be worn alone

Necklace Length and Proportions

When choosing between an 18mm vs 20mm chain, think about the necklace length and how it will affect the proportions of your pendants. An 18mm chain works well for many pendant sizes. Its slightly thinner profile allows for better balance with smaller or more intricate designs. It can be worn alone for a minimalist look or layered with other chains of different lengths and widths for a more dynamic appearance.

A 20mm chain, because of its increased width, pairs well with larger, bolder pendants like a chunky cross or a statement medallion. However, it may overpower delicate or small pendants. A popular example of this is the 3-row 20mm Cuban link chain in 14k gold, which has become a trendy choice for those looking for a bold and impactful statement piece

However, it may not work as well with delicate or small pendants, as they may seem overshadowed by the chain’s thickness. Keep the size and style of your pendants in mind when deciding between these two widths.

Comfort and Wearability

18mm Chains

  • Are generally more comfortable for long periods of wear
  • Spread weight evenly across the neck, reducing discomfort
  • Are good for everyday wear or those with sensitive skin

20mm Chains

  • May feel heavier around the neck due to their larger width and weight
  • Some people like the feeling of a heavier chain, while others may find it less comfortable

Necklace Length Options

When selecting between an 18mm vs 20mm chain, it’s important to consider the necklace length that best suits your style and body type.

Here are some common necklace lengths:

Choker (14-16 inches)

  1. Sits close to the neck
  2. Good for shorter necks or petite frames
  3. Can make a bold statement when paired with an 18mm or 20mm chain

Princess (17-19 inches)

  1. The most popular and versatile length
  2. Sits just below the collarbone
  3. Works well with many necklines and outfits

Matinee (20-24 inches)

  1. Falls between the collarbone and the bust
  2. Good for layering with shorter necklaces
  3. Can elongate the neck and draw attention to the décolletage

Opera (28-36 inches)

  1. Falls below the bust, often reaching the navel
  2. Can be worn alone for a dramatic look or layered with shorter necklaces
  3. Good for taller individuals or those seeking a more elegant, formal look

Think about your personal style, body type, and the necklines of your clothing when choosing the best necklace length to pair with your 18mm vs 20mm chain.

Materials and Durability

18mm vs 20mm chains are available in various materials, including gold, silver, and stainless steel. Durability depends on the material quality and craftsmanship.

While a 20mm chain may appear more durable due to its increased thickness, it’s crucial to select a high-quality chain regardless of width.

Gold and silver offer a luxurious look but require careful maintenance, while stainless steel is known for its strength and resistance to tarnishing, making it a practical choice for everyday wear.

Ultimately, investing in a well-crafted chain from a reputable brand ensures longevity and enjoyment of your jewelry piece

Mixing and Matching

One great thing about both 18mm and 20mm chains is that they can be mixed and matched with other chains and jewelry pieces. Layering chains of different widths, lengths, and textures can create a unique, personalized look that shows off your individual style. When mixing and matching, think about the overall balance of the pieces so your look isn’t too overwhelming.

Trends and Fashion

In recent years, bold, statement chains have become more popular, with the 20mm chain gaining attention from those who want a more substantial and daring look.

However, the 18mm chain is still a classic and timeless choice that offers versatility and comfort for everyday wear.

Price Considerations

The price difference between 18mm and 20mm chains is usually minimal, especially when investing in a high-quality piece. Rather than focusing on minor price variations, prioritize the quality of materials and craftsmanship, as well as your personal preferences.

A well-made chain, regardless of width, is a worthwhile investment that will last longer and save you money in the long run by avoiding the need for frequent replacements. Choose the chain that best suits your style and budget for optimal satisfaction.


Deciding between an 18mm vs 20mm chain comes down to your personal style, comfort preferences, and the types of pendants you want to wear. An 18mm chain offers a more understated and versatile look, while a 20mm chain makes a bolder statement. Think about your individual needs and the look you want to achieve when making your choice.

Also, consider the necklace length and how it will work with your body type and clothing styles. By investing in a well-made chain that reflects your taste and complements your lifestyle, you’ll have a piece of jewelry you’ll love wearing for years to come.
