Size & Fit Guide

Body measurements go around you. Garment measurements describe the item, often laid flat. Use a body-size chart with body measurements and a garment chart with garment measurements.

Take measurements without stretching the fabric. Check each chart’s measuring points and whether an elastic waist is relaxed or stretched. Use centimetres or inches consistently: 1 inch = 2.54 cm.

Use the product-specific chart when one is available. Where measurements have not yet been verified, the product page says so. There is no universal RKsignature size conversion chart.

Lay a similar garment flat, fasten closures and smooth it without stretching. Compare the same measuring points for the exact style.

Chest width

Measure straight across below the armholes. This is a flat width, not your body chest circumference.

Body length

Measure from the highest shoulder point beside the neck to the hem.

Shoulder & sleeve

Measure shoulder seam to shoulder seam, then sleeve from shoulder seam to cuff. Raglan sleeves use a different starting point.

Fasten a pair you like, lay it flat and smooth it without pulling the waistband. Record elastic waist measurements relaxed.

Waist width

Measure across the waistband. A flat waist width and a waist circumference are different measurements.

Hip width

Measure across the widest part of the seat, matching the chart’s measuring point.

Rise & inseam

Measure front rise from crotch seam to waistband; measure inseam along the inner leg from crotch seam to hem.

Compare a pair with similar stretch and fit. Take flat measurements with the fabric relaxed; these differ from body measurements.

Body waist & hips

Keep the tape level around your waist and fullest hips, snug without pulling tight. Use these only with a body-size chart.

Garment waist & rise

Lay leggings flat without stretching. Measure waistband width and front rise from crotch seam to waistband.

Inseam

Measure along the inside leg from crotch seam to hem. Check the exact style length.

Fasten a similar skirt and lay it flat without stretching the waist or fabric.

Waist width

Measure straight across the waistband with elastic relaxed.

Hip width

Measure across the widest part, matching the chart’s measuring point.

Length

Measure from the top of the waistband to the hem. Check front and back for an uneven hem.

One Size is a label; use the actual adjustment range to check fit.

Head circumference

Wrap a flexible tape around your head just above eyebrows and ears, level and comfortably snug.

Adjustment range

Compare your head measurement with the confirmed minimum and maximum circumference.

Knitted headwear stretches. Relaxed flat width is not the head circumference it will fit.

Head circumference

Measure around your head above eyebrows and ears, keeping the tape level.

Beanie dimensions

Compare relaxed width and height with a beanie you like. Confirm whether height includes a folded cuff.

Check usable compartment dimensions as well as exterior dimensions when choosing a bag for a laptop or other belongings.

Width, height & depth

Measure a similar bag closed from its outside edges. Exterior dimensions do not establish what fits inside.

Strap & handle

Compare the adjustable strap range or handle drop with a bag that sits comfortably on you.

Compartment fit

Measure the item you intend to carry, including its case. Check the opening and usable internal dimensions.

Check the product’s stated foot-length or shoe-size range. One Size does not establish sock fit.

Foot length

Standing on paper, mark heel and longest toe. Measure between them; check both feet and use the longer measurement.

Size system

Use the stated UK, US or EU range for the exact product. These labels are not interchangeable.

Choose by confirmed capacity and dimensions rather than clothing size.

Capacity

Check whether the listed capacity is total volume or usable fill level.

Height & diameter

Compare assembled dimensions with your storage space. Check the widest point for a cup holder.

The same size label can fit differently between styles. Compare the garment shape, measuring points and fabric stretch. Campaign images show styling; model proportions alone cannot establish your size.

For help with a specific style, include its name, your usual size and the measurements of a similar item you like in your message to support@rksignature.com.
