How the JoyaGoo Spreadsheet Step Grid was measured
Which estimator queries sit behind the numbers, which weights we sampled and which we did not, what has changed since the first reading, and who keeps this site.
Readings behind every number
Every figure on this site comes from JoyaGoo's public shipping estimator, queried on 17 October 2026 through the same request the estimator page makes, with the estimation flag set. We saved all 376 responses with the destination, weight and box size in the file name.
We first repeated an earlier reading (six destinations, one kilo, a 30 × 20 × 10 cm box) and got the same result: 23 of 37 line listings billed one kilo as 1,100 g. We then queried 22 destinations at three weights and probed band edges and limits at 47 weights in all, using a 15 × 10 × 5 cm box so that actual weight, not size, governed.
The step pairs come from the response fields for first and continued weight. Every priced result was checked against the rule first weight plus started steps; all 1,941 matched. Four browser sessions confirmed what the result cards and Detail panels display.
Revision notes for the step data
Last updated 17 October 2026. This is the first reading, so there is nothing yet to compare it with; 31 October 2026 is the next editorial review target, not an automatic update or a promise of current availability.
When a reading changes something (a new line, a different pair, a moved band edge, a new limit) the change log here will name the line, what changed, both values and the reading date, and affected tables and explanations should be checked against the new evidence.
What we did not sample: weights between our probe points, and destinations beyond the 22 the estimator lists at the top of its menu. A band change hidden between two sampled weights is possible; the finder page says so too.
Official notices and current offers
JoyaGoo posts official announcements on its site, and in October 2026 it was running seasonal coupon events alongside a VIP Center that opened in September 2026. We do not list coupon values here: they expire quickly, and the estimator's discounted figure is a display assumption rather than a price you are promised.
What does matter for this site is any official notice about weights or lines. None of the help pages we read on 17 October 2026 mentions step rounding; if one appears, we will cite it here with its date.
For anything time-limited, read the announcement itself on the official site, check its end date and the time zone it uses, and keep a screenshot.
The official Discord and other places shoppers talk
The only community link in JoyaGoo's footer is its official Discord server, and we checked that the invite resolves to a server named JoyaGoo. Check any announcement against its official terms and expiry; the sources do not establish which channel publishes first. Member counts move hour by hour, so we do not quote one.
The 2025 rename notice also named a subreddit; we failed to confirm it and left it unlinked. Reddit threads, YouTube hauls and TikTok clips can be useful for real experiences with a line or a seller; treat weights quoted there with care, because people rarely say whether they mean actual or billable weight.
If you share a parcel weight in a community thread, give the gram figure and the line name. It makes the reading checkable.
The people and process behind the grid
This site is an independent reference, not affiliated with JoyaGoo and not paid by it or by any seller. It provides independent buying guidance based on dated public sources and retained calculation evidence; it does not claim personal purchases or warehouse visits.
Pages are generated from the saved estimator responses, and their displayed explanations are reviewed separately; generation alone cannot prevent an error. Links to JoyaGoo and to the product catalogue carry a visit tag that identifies this site; there is no affiliate code and no referral link.
Corrections go to [email protected]. If you think we have something wrong, send the evidence and we will check it against a fresh query.

The oldest source is the page that ought to explain weighing, and it describes channel names the estimator no longer uses. That gap is the reason this site reads the estimator directly.
