# sizeRun

query · in the family [Size run](/reference/size-run/)

## What it does

Look up one record — a size run — the ratio a buyer spreads a quantity over one option dimension (S-M-L-XL 1-2-2-1), kept once and reused by every style that names it.

A SizeRun by id, within the caller's OWN org-group family; requires authentication. A cross-tenant id reads as null (not-found) AND trips the rootId tripwire server-side.

## What happens

Reads only — changes nothing.

## Who may call it

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `id` | [ID](/types/#scalars) `ID!` | yes | The id of the record. |

## Returns

[SizeRun](/types/SizeRun/) — A size run — a RATIO over ONE option dimension (S-M-L-XL 1-2-2-1; a colour run 2 black: 1 white is equally real — any OptionGroup type may carry a run) a buyer fills a matrix with: kept ONCE and reused on every Style that names it (Style.sizeRunId — its group must be in the scheme) or by the dimension itself (OptionGroup.defaultSizeRunId — the org default lives on the dimension); resolution = the style pick, then the group default, then none (the matrix axes carry the resolved id). optionGroupId is IMMUTABLE at birth (a different dimension is a DIFFERENT run: doom + create — the PurchasePack unitsPerPack stance). entries = 1..256 { optionValueId, share } rows — DISTINCT values OF THAT GROUP, every share an integer 0..10000, the shares summing to at least 1, stored in the CALLER order = the display order (a 0-share value rides the run but never receives a unit). sizeRunFill spreads a total over the ratio by the fill rule (largest remainder, ties to the earlier entry, the quantities summing to the total exactly). Doom is blocked while a non-doomed Style or OptionGroup names the run (CONFLICT/REFERENCED naming the holders); deactivate is free. Group-parented (parentId === rootId); sysId SZ-….
