Enter the exact dimension type and unit before comparing hoop sizes. The diagram can show consistent relative scale, but it cannot predict ear clearance or worn appearance without piercing position, anatomy, profile, and closure details.

A measurement-labelled hoop comparison tool that separates outer diameter, inner opening, thickness, face width, total drop, and closure geometry.

What this guide covers

Choose the exact hoop dimension being entered.
Normalize the unit and draw a consistent-scale comparison.
Confirm the product and wearer details outside the tool.

Name every input before using the number

A value is useful only when its measurement convention and source are clear.

Dimension type

Select outside diameter, inside opening, overall width or height, tube or wire thickness, total drop, or another explicitly defined measure.

Value and unit

Enter the stated millimetres or inches and retain the original value; use 1 inch equals 2.54 centimetres only for transparent conversion.

Product context

Record profile, setting, post or wire path, hinge and latch, orientation, and whether the measurement is maker-supplied or user-measured.

Build the visual without inventing missing dimensions

The tool compares known measures and leaves unknown geometry visibly open.

1 — Validate the label
Reject a bare size when the seller has not said whether it is an inner, outer, or total dimension.
2 — Convert once
Use the NIST relationship, retain reasonable precision, and display both the original and converted values.
3 — Draw one scale
Place alternatives on the same diagram scale with dimension lines rather than resizing each hoop to fill its own frame.
4 — Attach the unknowns
Keep piercing location, ear anatomy, angle, profile, closure path, and photo perspective beside the result.

Read the diagram as a size comparison

The result can organize measured alternatives; it is not a virtual try-on.

Relative outline

Compare one labelled dimension across options on a common scale without treating the outline as the complete earring.

Opening context

Use a known inner opening only when supplied, and keep thickness, post, hinge, latch, and settings visible as separate inputs.

Wearer confirmation

Take the selected dimensions to an actual try-on or product-specific review for clearance, position, closure, and comfort.

The picture cannot guarantee the fit

Tool boundary
Ear anatomy, piercing location and angle, product profile, closure path, perspective, and measurement error can change the worn result. The tool promises no clearance, comfort, closure alignment, or appearance.
