apple-touch-icon iOS Sizes Lookup
Bounded common square pixel icon hints; actual device/browser recommendations vary and no complete current iOS table asserted.
Description
apple-touch-icon iOS Sizes Lookup: look up a supported built-in reference entry.
A touch-icon size is a pixel-dimension hint associated with a particular platform profile. Historical device hints differ from a universal current requirement.
This tool returns a built-in reference entry for an exact supported selector. The supported entries and their scope are part of the tool; no website or current external table is queried.
When to use this tool
Use this tool when the supplied inputs match the specific operation described above and you need a repeatable result under its stated convention.
- Check the supported input and output contract against an existing calculation or observation.
- Use the complete example to confirm units, selector spelling and result interpretation.
How to use the tool and how it works
- Enter every field in the input table using the stated units and the exact supported selector spelling where applicable.
- Run the tool. Correct input errors before interpreting an output.
- Read the result fields below; use accompanying flags and the stated sign, boundary or model convention when interpreting a number.
Select one supported profile and return its stored width and height: 180, 120 or 152 pixels per side.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| profile | Profile. | Exact value: "common-modern-hint", "historical-iphone-retina-hint", "historical-ipad-retina-hint" |
| profile | Built-in entry |
|---|---|
| "common-modern-hint" | [180,180] |
| "historical-iphone-retina-hint" | [120,120] |
| "historical-ipad-retina-hint" | [152,152] |
| Output field | Interpretation |
|---|---|
| result | Object containing the following named result fields. |
| result.reference | The stored entry for the exact selected key; its type may be text, a number or a list. |
{
"input": {
"profile": "common-modern-hint"
},
"output": {
"result": {
"reference": [
180,
180
]
}
}
}Limitations and assumptions
- The tool does not inspect an icon or verify current device requirements and platform support.
- Every declared field is required and unexpected fields are rejected. Numeric inputs must be finite; input errors are distinct from a valid false result or an explicitly qualified output.
- Extremely large inputs and nonfinite or excessively large outputs are rejected. List positions reported by the tool use zero-based indices unless stated otherwise.
Alternative or Complementary methods
Check the underlying observations, units and conventions independently before using the result in a larger workflow. The tools listed below address nearby tasks; compare their inputs and scope before substituting one for this operation.
