iTaoBuy Spreadsheet size guide for shoes and clothing

The cards here display a listing title, image and reference price, with a QC count on some records. They do not include measured dimensions, a verified size chart or a fit review. Open the linked product page and select the exact model, color and size option before using any chart shown there.

Check the chart’s units, the part being measured and whether it belongs to that exact item. A generic brand chart is a starting point, while a product-specific chart may describe a particular cut. Neither proves how the item will feel on your body. Keep the product URL, selected option and chart together so you can revisit the same information before checkout.

To establish a foot-length reference, stand on paper on a firm surface, mark the back of the heel and the end of the longest toe, then measure between the marks. Repeat for the other foot and use the longer measurement when consulting the shoe’s size chart. Nike gives this method in its footwear guide; REI also recommends measuring length and width and considering the larger foot.

Read the column heading before comparing numbers. “Foot length,” “insole length” and a CM/JP size printed on a shoe label are not automatically the same measurement. Nike expressly notes that the CM value on its shoe box or label differs from the foot-length column in its own chart. A familiar EU or US number should therefore be checked against the relevant model or brand chart rather than converted using a rule borrowed from another seller.

Width and shape still matter after you find a length candidate. If a previous pair felt tight through the forefoot or heel, look for width information and the stated fit of this model. A catalog picture cannot tell you the internal shape or comfort of the shoe.

A body-size chart may give a chest or waist circumference measured around the wearer. A product-size chart may give the finished garment’s width while it lies flat. Those figures cannot be compared directly. UNIQLO’s product-measurement guidance makes this distinction and recommends comparing a listed garment with a similar item you already own.

For example, if your well-fitting T-shirt measures 52 cm across the chest from underarm to underarm when laid flat, and a listing states 54 cm using the same method, the listed shirt is 2 cm wider across that flat measurement. That comparison does not by itself predict the full fit: shoulder shape, fabric stretch, cut and measurement methods may differ. The numbers in this example are illustrative, not measurements of a product in this directory.

Write down the unit and method beside each number. Converting inches to centimeters is valid arithmetic, but it will not fix a comparison between a body circumference and a flat garment width. If the listing simply says “chest 54” without defining it, ask what was measured.

For a T-shirt or hoodie, compare flat chest/body width and body length first, then shoulder and sleeve measurements where provided. Lay a similar top you already like on a flat surface and measure it using the same points described by the listing. UNIQLO’s guide uses chest width, body length, shoulder and sleeve as distinct product measurements; a single “M” label does not describe all of them.

For a jacket or down-jacket listing, consider the clothing you intend to wear underneath. Compare the listed garment dimensions with an outer layer you own that fits over those clothes. Check sleeve and body length as well as width; a roomy chest does not fix sleeves that are too short for your preference.

Do not infer measurements or filling from a model photograph or thumbnail. If the listing calls a garment “oversized” but offers no useful dimensions, that word describes a style intention, not the amount of room it will give you.

For pants, look for waist, hip or seat, thigh, rise and inseam measurements when available. Inseam is the length along the inside leg from the crotch toward the hem; Levi’s and UNIQLO both explain it in their size guides. Rise and leg opening can change how trousers sit and look even if the labeled waist and inseam appear familiar.

Check whether “waist” is a body circumference, a finished garment circumference or a flat waistband width. An elastic or drawstring waistband may also have a range, but do not invent one if the listing omits it. Measure a pair of pants you like at the same points, including the inseam and waistband, then compare like with like.

For shorts, inseam and leg opening may matter more to your preferred length and silhouette than the size letter alone. A photo can show the intended style but cannot establish a measured inseam without a reliable scale or chart.

If a listing offers only “M,” “EU 42” or an unexplained centimeter number, do not turn it into a guaranteed fit by applying a universal conversion or automatically sizing up. Ask the seller or service that would take your order for the exact variant’s measurements and the definition of each chart column. A useful question is: “For this selected size, is the 54 cm chest figure a flat underarm width or a body circumference?”

If two charts on the same page disagree, confirm which one belongs to the selected item before paying. If no one can clarify a dimension that matters to you, compare another listing with better information. A QC photo of a size label can show the printed label, but it cannot establish fit; read the applicable exchange or return terms separately if a wrong size would be costly to correct.
