A useful Kakobuy size chart is one you can connect to a real garment, a clearly measured body dimension and the way you intend to wear the item. A remembered size letter is less useful when your next choice has a different shape. Start by deciding which part of an existing fit you want to keep and which part you want to change.
The aim is not to build a universal conversion table. It is to leave yourself a short, repeatable record so that every new candidate does not require starting from memory.
Choose a reference for the same job
Pick a garment you actually wear for the intended activity. A close underlayer is a poor reference for the width you want in an overshirt. Equally, a loose top that looks good standing still may not tell you enough about the length you prefer when sitting or tucking it in.
Before measuring, note two things: what works and what you would change. You might like the shoulder position but want less fabric at the hem. That is a more useful instruction than copying every measurement into the next purchase.
If nothing you own performs the proposed role, say so in your notes. Use the closest relevant garment while keeping the difference explicit. Do not turn an imperfect reference into an exact fit target just because it is available.
Record how you got the number
For a finished garment, follow the selected chart's diagram or written method. Lay a suitable garment flat, arrange it without pulling it into a larger shape and keep the tape straight between the stated points. Record the unit, endpoints and whether an elasticated area is relaxed or stretched. If the chart gives no method for an important dimension, ask before comparing.
A flat width across a top is not the same measurement as a tape taken around a person's chest. Do not double a width automatically and treat the result as the body size the garment will fit. Shape, intended ease and the chart's own definitions still matter.
Length also needs named endpoints. A centre-back length and a measurement beginning near the shoulder need not describe the same path. Sleeve lengths may begin at different points. Keep the method beside the number so that a later measurement is genuinely comparable.
You can keep this record simple: Item ID for the candidate, selected size, chart type, the few relevant dimensions and the unresolved difference from your reference. It does not need a field for every visible detail.
Use body measurements when the chart asks for them
A body chart should be compared with the person, not with a flat garment. Follow that chart's instructions. Common body-measurement methods take the chest around its fullest part, the waist around the natural narrowest part and the hips around their fullest part, keeping the tape horizontal. A chart may name a different point; its definition matters for that comparison.
Avoid adding a fixed allowance to every body measurement. A chart can already be designed around an intended fit, and the amount of room you want changes with the garment's role. If the chart does not explain how its body range relates to the product, keep that question open rather than inventing a conversion.
For someone else's item, use their own current measurements and preferences. Two people selecting the same size letter are not necessarily asking for the same fit.
Change one fit decision at a time
Use clothes you already own to explore the proposed combination. Put the intended layer underneath your reference jacket. Sit in the trousers at the waistband position you normally use. Notice where the combination becomes awkward before deciding which dimension to investigate.
This does not test the new item. It helps you ask a better question about it. If the reference jacket pulls only when worn over a thick layer, investigate the relevant shape and dimensions instead of assuming that every part of the next jacket must be larger.
The tops guide develops neckline, hem and layering choices; the pants and shorts guide considers seated fit and waistband position. Use this page to keep the measurements consistent across those different decisions.
Keep footwear in a separate comparison
A shoe size label should not be substituted for measured foot length. Where a footwear chart asks for foot length, use its method. For the paper method, secure the paper on a hard, flat surface and stand with one foot on it while keeping your weight balanced across both feet. Mark the heel and longest-toe positions with the marking tool upright, then step off and measure between the marks. Measure both feet and use the longer length when following that chart's instructions.
Do not add a universal extra distance or assume that every centimetre-labelled size is a direct foot-length measurement. Width, shape and intended use require their own consideration. The shoes guide helps connect those questions to the pair's place in your daily outfits.
Carry the same record through arrival
When reviewing warehouse photographs, connect the visible item to the selected option. If a measurement view is available, read its endpoints and tape position before comparing it with your notes. Ask about an unclear view; do not assume a requested measurement or additional photograph is included automatically.
The official English inspection guidance read on September 7, 2026, names appearance, model, style and size. A photograph is not a wear trial. Our QC photos guide explains how to turn a specific uncertainty into a useful question.
After receipt, try the item in the combination that motivated the purchase. Record whether the difference you wanted actually helped. If fit changes later, retain the care instructions, what you did and the measurement method; a change in one garment does not establish a rule for the next one. That short history makes a future shortlist more useful than another size letter alone.

FAQ
Can I use the same size across my whole parcel?
Compare each selected chart separately. Matching letters do not establish matching dimensions or a shared fit.
Which measurements should I keep?
Keep those relevant to the fit decision, with the object measured, unit, endpoints and garment state. A number without its method is difficult to reuse.
Should I go up a size when I want more room in one area?
First identify the area and compare the available dimensions. Changing the overall size may also change parts of the fit you already like.
Can a warehouse image settle comfort?
It may help with visible details or a clearly shown measurement. Comfort during your own movement and wear remains a separate question.
