Paddock Size Calculator

Reconcile a completed, source-owned paddock boundary and exclusion schedule into usable area without inventing stocking or welfare approval.

Use this result well

Inputs that matter
One de-identified completed paddock usable-area record scope and basis; responsible survey, GIS, conservation, land-management or reviewed source plus revision/date; exact parcel/site context; boundary method/reference/date; inclusion/exclusion policy; horse group/use context and whole count; gross-boundary and aggregate-exclusion source/value/unit rows; and an optional independently prepared same-boundary usable-area source/value/unit
Output to expect
Preserved source ownership, exact acres/hectares/square-feet/square-meters normalization, source-recorded usable area, excluded share, descriptive area per recorded horse and optional signed computed-minus-independent same-boundary difference
How it works
Validate every source and unit, normalize completed gross and excluded areas with exact NIST relationships, subtract only source-recorded exclusions, divide by the whole recorded horse count descriptively, then reconcile an optional independent usable-area record covering the identical boundary and policy
  • Confirm that parcel identity, boundary method/reference/date, source precision, gross area, exclusions, horse group/use period and independent value all belong to the same completed record. An address, map screenshot, subjective land quality or area from another boundary is not interchangeable evidence.
  • Use the result only for area-record transcription and arithmetic QA. It does not establish a minimum acreage, legal boundary/title, stocking/carrying capacity, forage or nutrition, grazing/rest/rotation schedule, dry-lot adequacy, parasite/mud/runoff/welfare outcome, permit/code, facility design, health or veterinary approval; use current survey/GIS, local NRCS/extension/conservation planning, applicable authorities and qualified professionals.

Choose your path

Built around the job you need to finish

Reproduce and reconcile one de-identified, source-owned completed paddock gross-boundary minus aggregate-exclusions usable-area schedule without inventing stocking or welfare approval.

Land manager transferring a completed parcel schedule

Preserve the responsible boundary and exclusion arithmetic without a generic website replacing the site-specific plan.

Name the source/revision, parcel, boundary method and inclusion policy, then copy gross and aggregate excluded area in their original units.

Gets auditable usable-area conversions and an excluded share while the responsible land plan retains authority.

GIS or survey technician checking a handoff

Catch a unit or transcription discrepancy between two exports that describe the same completed geometry.

Enter the completed source schedule and optionally add one independently prepared same-boundary usable-area source/value/unit.

Sees exact signed area and percentage differences without the website claiming legal-boundary or survey validation.

Equine facility team documenting planned use

Record which whole horse group and turnout purpose accompanied the completed area schedule without turning the ratio into a capacity recommendation.

Preserve the group/use context and whole recorded count, then review descriptive area per recorded horse alongside the site record.

Can hand the reconciled record to local conservation, pasture, welfare and professional planning with no automated care verdict.

How it works

Preserve One Completed Boundary Schedule

Copy the responsible source, revision, parcel context, completed boundary method and exact inclusion/exclusion policy. Do not combine a gross area, exclusions or independent value from different maps, dates, coordinate systems or boundary definitions.

One parcel + one measurement reference/date + one inclusion/exclusion policy

Normalize and Subtract Source Areas

Convert acres, hectares, square feet or square meters with exact NIST relationships, require exclusions to remain below gross area, and report usable area plus excluded share. Unit conversion preserves arithmetic but does not add survey accuracy.

Usable area = Gross boundary area − Aggregate source-recorded exclusions

Reconcile Without Approving Capacity

An optional independent source/value must describe the identical boundary and exclusion policy. The signed difference checks transcription; agreement does not validate legal title, soil/forage assumptions, stocking capacity, dry-lot adequacy or welfare.

Difference = Computed usable area − Independent same-boundary usable area

Example Scenarios

Enter the source-owned 4.5-acre gross boundary and 0.75-acre aggregate of buildings, lanes, water and buffers. The worksheet reports 3.75 acres usable and preserves the exact exclusion policy without calling it sufficient pasture.

Normalize a completed hectare boundary and square-meter exclusion row, then compare the computed usable area with an independently exported acre value for the same geometry and revision.

Record the exact three-horse turnout group and completed usable area to produce a descriptive acres-per-recorded-horse ratio. Use separate local conservation, pasture, nutrition and welfare planning to decide what the land can support.

FAQ

No. It reports one completed source record's usable area and a descriptive area-per-recorded-horse ratio. Soil, climate, forage production and condition, management purpose, horse class and weight, rest, supplemental feed, water, shelter, drainage and local requirements all remain outside this arithmetic.

Use only the completed source schedule's explicit policy. It may identify buildings, lanes, water, wetlands, buffers, woods, slopes, reserved areas or other non-turnout geometry, but this website does not choose or discover those exclusions.

Yes only when the responsible completed schedule explicitly records zero aggregate exclusions under its stated policy. A blank or missing exclusion review should not be represented as zero.

A numeric difference is meaningful only when both records use the same parcel geometry, revision, measurement reference and inclusion/exclusion policy. A close match checks arithmetic and transcription; it does not validate either source.

Use current survey/GIS records, local NRCS and extension resources, a site-specific conservation or pasture-management plan, applicable authorities and qualified equine, forage, soil, drainage, legal and veterinary professionals. This worksheet does not approve those decisions.

About Paddock Size Calculator

Reproduce one de-identified completed paddock usable-area schedule from its responsible survey, GIS, conservation, land-management or reviewed training source. Preserve the exact boundary method, inclusion and exclusion policy, parcel and horse-use context, then subtract the source-recorded aggregate exclusions and optionally compare the result with an independently prepared same-boundary usable-area value. This is area-record arithmetic, not a minimum acreage, stocking, forage, grazing, dry-lot, welfare, legal, regulatory, facility-design or veterinary decision.
