Circle Crop Methodology

Circle crop methodology is why a size or a menu name appears on this site. A figure is included only when that company’s help page states it. Geometry uses the same formulas as the editor.

Two kinds of facts

This site prints two kinds of facts, and they are not mixed. A platform size comes from that company’s help page. A geometry figure comes from the crop formulas. LinkedIn’s pixel range does not belong inside the formula for the area of a circle, and the area of a circle is not a platform’s upload rule.

The size chart and the geometry page stay separate so you can tell which kind of sentence you are reading. A number with a help-page link and a date is a quotation from that company, checked on that day. A number with no such link is either this site’s labeled suggestion, or a calculation. Circle crop methodology keeps those two kinds of facts on different pages.

How a platform size is recorded

Circle Crop Image Team opens the company’s help page and records only what that page states: a pixel size, a range, a file type, or a file-size cap. The URL and the date of the reading stay with the row. The HTML table, platform-sizes.json, and platform-sizes.csv are all produced from that same record, so a cell on the page and a cell in the download are not kept as two independent copies.

If the help page does not publish one pixel size, the row says so. 512 by 512 is then labeled as a general recommendation from this site, not as the company’s rule. On the dates in the table, Discord, Instagram, WhatsApp, TikTok, and X were in that group. LinkedIn’s cited page gives a range, so the table does not pretend there is one recommended square. YouTube’s branding article says the channel picture renders at 98 pixels, and a different article gives 800 pixels for an official artist avatar. Those are two claims, and the page keeps them apart. Circle crop methodology does not merge them into one official square.

What the date on a row means

Each row shows the day the help page was last read. A date older than 180 days means the row is due to be opened again. It does not mean the company changed the rule that morning, and it does not mean the old sentence is still right. If the help page disappears, the official number is removed and the gap is labeled. A missing page is not replaced with a number from memory, or with a figure from another site’s chart.

You can do the same check. Open the source link on the platform page, read the size it states, and compare it with our sentence. If they disagree, write to us with that URL, the sentence on our page, and a short quotation from the help page. The row and the date are updated together. Circle crop methodology treats that date as the day the page was read, not as a promise the company still agrees.

How the geometry numbers are produced

The share of a square that a circle covers, the safe square inside the circle, the scale Fit uses, the way a border is rounded, and the share of a 3:2, 4:3, or 16:9 photo that remains inside the circle are calculated when the site is built. They are not typed into the article by hand. The geometry page and the editor use the same formulas, so a change in that rounding shows up in the article rather than drifting away from the tool.

A requested diameter above 4096 pixels is limited to 4096, because that is as large as the editor will export. Choosing the original size does not enlarge a crop that is already smaller than the photo. Those rules are part of the same calculation. The article can state them because it is reading the calculation, not guessing a round number that looks close. Circle crop methodology prints the figure the build returns.

The downloadable size table

The size chart is also published as platform-sizes.json and platform-sizes.csv. Use those files when you want the same rows outside the HTML page. A license for copying them into another project has not been chosen. You may read them here. Do not treat them as public-domain data, and do not present a row as the platform’s current rule without opening the source link and noting the date.

This page is the update rule. It is not a promise that every number stays current by itself. The date and the link are the part you can check without taking the sentence on faith.
