Plus Size Rings Are More Available in Australia Than Ever

Most standard AU ring size charts stop at AU Z, but many Australian jewellers — including custom and online specialists — stock or can make rings up to AU Z+15 (US 16+, 26.3 mm inside diameter). If your finger measures larger than standard ranges, you are not alone and you have excellent options. Accurate measurement and knowing what styles suit larger fingers makes finding the perfect ring straightforward.

❓

What Is a Plus Size Ring?

The Definition

📏

Most people fall between AU size F and AU size Z (US 1 to US 12½). A plus size ring is generally considered any size above AU Z — starting from AU Z+1 (US 13) upward.
💍

Standard jeweller stock typically covers up to AU Z. Sizes AU Z+1 through AU Z+15 are considered extended or plus sizes and may need to be ordered specially or custom made.
🛍️

Some retailers define plus size from AU W or X onward because standard stock in those larger letter sizes can be limited — always check before purchasing online.

Who Needs a Plus Size Ring?

👤

Larger hands generally. Finger size relates to overall hand and body size, but is not always predictable. Slim people can have larger knuckles; fuller people can have smaller finger bases.
🧬

Arthritis or joint swelling. Joint conditions can significantly widen knuckles, requiring a larger ring size to pass over the knuckle even if the finger base is average.
💪

Manual workers and athletes. Regular heavy work or sport can increase finger and knuckle size over time. Ring size can change through adulthood with lifestyle changes.
👨

Men with larger builds. Men's average sizes are AU R–V, but larger men or those with wider hands often need AU W through AU Z+5 or beyond.

How to Measure Plus Size Ring Fingers Accurately

⚠️

Standard Ring Sizers Often Don't Go Large Enough

Most jeweller ring sizer kits and printable guides only go to AU Z. For larger fingers, the paper strip method and digital calliper are your most reliable options at home. Ask jewellers specifically if they have plus size metal ring sizers before visiting in store.

Method 1 — Paper Strip (Recommended for Large Fingers)

🎯 Best for any size · ±0.5 mm · No upper size limit

Cut a strip of paper ~1 cm wide and 12 cm long

Use a longer strip for larger fingers to ensure comfortable wrapping without running out of paper.

Wrap firmly around the finger base

Wrap at the base of the finger where the ring will sit. For larger fingers with wider knuckles, also check the knuckle passes through comfortably.

Mark the overlap and measure in mm

This is your circumference in mm. Find it in the Circumference column of the extended size chart below.

Measure both base and knuckle

For larger fingers, if the knuckle is wider, measure both. Choose a size between the two so the ring fits over the knuckle without spinning at the base.

Method 2 — Digital Calliper

⭐ Most accurate for large sizes · ±0.2 mm · ~$20 at Bunnings

Zero the calliper before measuring

Close jaws fully and press zero to reset.

Measure across the widest part of the finger

For larger fingers, this may be the knuckle rather than the base. Measure both and note both readings.

Record in mm — this is your diameter

Multiply by 3.14 for circumference, or look directly in the Diameter (mm) column of the chart below.

Choose the larger reading if base and knuckle differ

The ring must pass over the widest point. If the knuckle is larger than the base, size to the knuckle and use a ring guard or sizing beads to keep the ring snug at the base.

⚠️ The Knuckle Rule for Plus Size Fingers

📏

If knuckle = finger base: Measure once at the base. Standard fit applies — use that AU size from the chart.
📏

If knuckle > finger base by up to 2 mm: Size to the midpoint between the two readings. The ring will slide on and off with a slight snugness at the base.
📏

If knuckle > finger base by 3 mm or more: Size to the knuckle. Use ring sizing beads (small gold or platinum beads fitted inside the band) to prevent spinning when worn. Most jewellers can add these.
🛍️

Hinged or split-shank rings: These designs open slightly to pass over a wide knuckle, then close snugly at the base. A great option if resizing is not possible for your chosen metal.

Conversion Formulas

Circumference → Diameter

Diameter (mm) = Circumference (mm) ÷ 3.14159

Example: 70.2 mm ÷ 3.14 = 22.3 mm → AU Z+1

Diameter → Circumference

Circumference (mm) = Diameter (mm) × 3.14159

Example: 22.3 mm × 3.14 = 70.0 mm → AU Z+1

Wide Band Adjustment (important for plus size)

Add ½ AU size for 5–7 mm bands · Add 1 full size for 8 mm+

Plus size rings are often wider — always account for band width

Knuckle Adjustment

Choose size midway between base and knuckle readings

Add sizing beads inside the band if the gap is more than 2 sizes

Ring Style Guide for Larger Fingers

💡

"Large fingers, large rings, small fingers, small rings"

Chunkier and wider rings create visual balance on larger fingers. Statement pieces draw the eye to the ring rather than the finger, while delicate thin bands can get visually lost and inadvertently highlight the finger size. The goal is proportion — not hiding, but complementing.

💎

Statement Solitaire

A bold centre stone draws the eye upward and creates a focal point. Works beautifully on larger fingers where a small stone can appear proportionally tiny.

✅ Highly recommended

🔵

Wide Band Rings

Wider bands (6–10 mm) add horizontal visual weight that balances a larger finger. Ensure you size up by ½ to 1 AU size to account for the wider contact area.

✅ Very flattering

✨

Pavé or Sparkle Bands

Rings with diamonds or sparkle all around catch light from every angle, drawing the eye to the glitter rather than the skin. Eternity-style bands work especially well.

✅ Great choice

💍

Oval and Elongated Stones

Oval, marquise, or pear-shaped stones create an elongating visual effect on the finger. Positioned with the point toward the nail, they are particularly slimming.

✅ Elongating effect

🪐

Cocktail and Cluster Rings

Large decorative rings with multiple stones suit bigger hands well. The proportionally bold design looks natural rather than lost on a larger finger.

✅ Works beautifully

🤏

Very Thin Delicate Bands

Ultra-thin bands under 2 mm can appear visually lost on larger fingers and may emphasise the skin around them. Not ideal, but choose personal preference above all.

💡 Choose personal taste

Where to Buy Plus Size Rings in Australia

✅ Best Options for Sizes AU Z+1 and Above

🏪

Local custom jewellers. Most Australian goldsmith studios can size any ring to order. Bring your mm measurement and specify both the inside diameter and the band width you need.
💻

Etsy Australian sellers. Many independent Australian jewellers on Etsy specialise in extended and custom sizing. Search specifically for "plus size ring AU Z+1" or your specific size.
🛒

Desiderate (Australia). An Australian jeweller that stocks sizes up to US 13 (AU Z+1) as standard and promotes inclusive sizing specifically. Based in Australia with AU shipping.
🛒

Francesca Jewellery (Australia). Offers guidance for large finger ring sizing with Australian sizing charts and in-store fitting options.

💡 Tips When Ordering Plus Size Rings Online

📐

Always provide your diameter in mm, not just an AU letter. Extended AU size notation (Z+1, Z+2 etc.) can vary between jewellers. Your inside diameter in mm is universal and unambiguous.
📦

Check the resize and return policy before ordering. Extended sizes are sometimes non-returnable as custom orders. Confirm before paying.
📏

Mention the band width you want. Jewellers need both the finger diameter AND the desired band width to make a correct custom piece.
🔁

Measure twice on different days. Extended sizing orders are harder and more costly to correct. Take measurements on at least two separate days to confirm consistency.

⚠️

Common Plus Size Ring Mistakes

❌

Ordering based on a standard chart that stops at AU Z. If your measurement goes beyond AU Z (21.9 mm diameter / 68.8 mm circumference), you need an extended size chart. Using the nearest standard size will result in a ring too tight to wear.
❌

Ignoring the knuckle when measuring. For many plus size fingers, the knuckle is the widest point. A ring sized only to the finger base will not pass over the knuckle at all.
❌

Not sizing up for wide bands. Wide rings feel tighter — always add ½ to 1 AU size for bands 6 mm or wider. This is even more important at extended sizes where sizing errors are harder to correct.
❌

Ordering a tungsten or ceramic ring without a confirmed exact size. These materials cannot be resized. For extended sizes, always confirm your measurement twice before ordering non-resizable metals.
❌

Measuring after exercise, heat, or a salty meal. Fingers can swell significantly in these conditions. For large fingers already prone to water retention, the difference can be up to 1–2 full AU sizes. Always measure at rest and at room temperature.

FAQ — Plus Size Rings Australia

What AU ring size is considered plus size in Australia? ▾

A ring is generally considered plus size when it is above AU Z, starting from AU Z+1 (US 13, approximately 22.3 mm inside diameter, 70.2 mm circumference). Most Australian jewellers stock up to AU Z as standard. Sizes AU Z+1 and above typically need to be ordered specially or custom made.

How do I measure my ring size if my finger is larger than a standard ring sizer? ▾

The paper strip method and digital calliper both work for any size with no upper limit. Cut a longer paper strip (12 cm+), wrap around the finger base, mark the overlap, and measure in mm. Alternatively, a digital calliper from Bunnings (~$20) gives an accurate diameter reading in mm which you can look up directly in the extended size chart. Standard ring sizer kits often stop at AU Z and are not suitable for plus sizes.

What ring styles suit larger or plus size fingers? ▾

Larger, bolder rings generally suit larger fingers best because they create proportion and visual balance. Statement solitaires, wide bands with sparkle or pavé setting, cocktail rings with large stones, and oval or elongated stone cuts (which create an elongating effect) all work especially well. Very thin delicate bands under 2 mm can appear visually lost on a larger finger, though personal preference should always take priority.

Can plus size rings be resized? ▾

Yes — gold, white gold, and platinum plus size rings can be resized by a custom jeweller, though costs are higher than standard sizes due to the additional metal required. Tungsten carbide and ceramic rings at any size cannot be resized and must be replaced. Always confirm the resize policy and associated cost before purchasing a plus size ring, particularly for custom pieces.

My knuckle is much wider than my finger base — what size do I order? ▾

Measure both the finger base and the widest part of the knuckle in mm. If the difference is less than 2 mm, choose the midpoint between the two readings. If the knuckle is 3 mm or more wider than the base, size to the knuckle measurement so the ring passes over comfortably, then have a jeweller add ring sizing beads (small gold beads welded inside the band) to prevent the ring from spinning when worn at the base. A hinged or split-shank ring is another excellent option.

Where can I buy plus size rings in Australia? ▾

Options include local custom goldsmith studios (available in all major Australian cities), Australian jewellers on Etsy who specialise in custom sizing, and dedicated inclusive jewellery brands like Desiderate (stocks up to US 13) and Francesca Jewellery. For the largest extended sizes (Z+6 and above), a custom order from a local goldsmith is usually the most reliable path. Always provide your inside diameter in mm rather than just an AU size letter, as extended notation varies between sellers.

Do fingers get bigger with age or weight changes? ▾

Yes. Fingers can widen gradually with age due to changes in bone density and joint size. Weight gain or loss also affects finger size — gaining 10 kg or more can increase ring size by 1–3 AU sizes. Arthritis, pregnancy, and lifestyle changes like manual work can all cause permanent or long-term changes. If your existing rings no longer fit, re-measuring with the paper strip method or a calliper is always a better approach than guessing an old size.
