Nordic Cross Offset Position Calculator
Nordic cross coordinate construction in hoist-left, top-left y-down frame from independently verified offset/width specification, not a universal family proportion.
Description
A Nordic-cross construction needs a horizontal position and an arm width in a declared flag rectangle.
A Nordic-cross construction needs a horizontal position and an arm width in a declared flag rectangle.1
This tool scales a verified vertical-stem offset and centers the horizontal arm on the hoist.
When to use Nordic Cross Offset Position Calculator
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Establish the flag dimensions, orientation, specification, palette, or visual annotations needed for this particular calculation.
How to use Nordic Cross Offset Position Calculator and understand its results
- Establish the flag dimensions, orientation, specification, palette, or visual annotations needed for this particular calculation.
- Enter hoist, fly, verifiedCrossCenterFlyFraction, crossWidth, following the field table and rules below, then run the tool.
- Read result. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| hoist | Hoist | number | Required |
| fly | Fly | number | Required |
| verifiedCrossCenterFlyFraction | Verified cross center fly fraction | number | Required |
| crossWidth | Cross width | number | Required |
Enter positive hoist, fly, and cross width and a stem-center fly fraction from zero to one. The width must fit the hoist and the vertical arm must fit the fly. Return center coordinates and two ordered edge pairs in a top-left, y-down frame.
cx=F×fraction; verticalEdges=cx±w/2; horizontalEdges=(H±w)/2 Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or reference | object |
| result.verticalCenterX | Vertical Center X | number |
| result.horizontalCenterY | Horizontal Center Y | number |
| result.verticalEdges | Vertical Edges | list |
| result.horizontalEdges | Horizontal Edges | list |

}Limitations and assumptions
The calculation uses supplied geometry, observations, or annotations. It does not establish an official construction specification, national identity, or universal design quality.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related review, use Nordic Cross Family Membership Checker: A Nordic-cross pattern combines a spanning orthogonal cross with a stem toward the hoist. This checker reviews three independent layout annotations rather than inferring a regional identity. For a complementary step, use Fimbriation Stripe Width Rule Calculator: Fimbriation adds a border on both sides of an inner stripe. Comparing the resulting outer width with a declared envelope makes an overrun visible as a negative remaining width.
