Which Fence Calculator Should You Use?

Most fence projects follow a simple flow: measure the runs, plan posts and spacing, then estimate materials and budget. Use the tool below that matches your step.

How to Measure Fence Length (Corners, Runs, Gates, and Returns)

Fence estimates start with accurate total length. Measure each straight run between corners, then add everything together. Don’t forget small “return” sections near a house, shed, or side gate—these are common reasons people under-estimate materials.

Practical measuring workflow

  1. Measure each run between corners (run A + run B + run C...).
  2. Note corners, ends, and any offsets (changes in direction).
  3. Measure gate openings separately (width) for planning posts and hardware.
  4. Account for slopes: steep yards may require stepped or racked sections.

Use the Fence Cost Calculator to turn total length into a planning budget estimate.

How to Calculate Post Spacing (On-Center, Panels, Corners)

Post spacing is commonly planned as on-center spacing—the distance from the center of one post to the center of the next. Fence style matters: pre-built panels often guide spacing, while picket fences can be more flexible.

Key post planning concepts

  • Corner/end posts: anchor each run and handle direction changes.
  • Line posts: fill the span between corners/ends.
  • Gates: typically need stronger posts and hardware planning.

For picket layouts and consistent spacing, use the Picket Fence Calculator.

Fence Post Depth Basics (Height, Soil, Wind, and Frost)

Post depth is a stability issue. The “right” depth depends on fence height, soil type, wind exposure, and local requirements. In colder regions, frost conditions can also influence depth planning.

Planning guidance (general)

  • Taller fences and higher wind exposure generally require deeper, stronger footings.
  • Loose or sandy soils often need more stabilization than dense soils.
  • Corner and gate posts may require extra reinforcement depending on design.

Use the Fence Post Depth Calculator for planning, then verify with local requirements and product guidance.

Estimating Materials and Cost (Posts, Rails, Pickets, Concrete, Hardware)

Fence cost estimates depend on more than length. Material choice, height, number of posts, gates, terrain, and labor assumptions can change totals significantly. A simple way to plan is to estimate core components, then verify packaging and local pricing.

Common cost drivers

Fastest budget workflow

  1. Measure total length and gate openings.
  2. Choose fence style and height.
  3. Estimate costs using a planning price per foot (varies by region/material).
  4. Adjust for gates, corners, slope, and site complexity.

Use the Fence Cost Calculator for a quick estimate and refine with local supplier pricing.

Fence Estimating Mini-Guides

These mini-guides show common planning workflows and which calculator to use at each step.

Budgeting a Basic Backyard Fence

  • Measure each run and total length.
  • Choose fence height and material type.
  • Estimate a planning cost and refine using local prices.

Use the Fence Cost Calculator.

Building a Picket Fence With Consistent Spacing

  • Measure total fence length (excluding gate openings).
  • Choose picket width and desired spacing.
  • Estimate total pickets and adjust for corners/ends.

Use the Picket Fence Calculator.

Planning Post Depth for a Taller Fence

  • Confirm fence height and note wind exposure.
  • Consider soil type and stability needs.
  • Plan depth, then verify with local requirements.

Use the Fence Post Depth Calculator.

Installing a Fence on a Slope (Stepped vs Racked)

  • Measure sloped runs carefully and note grade changes.
  • Choose stepped panels (level sections) or racked panels (angled sections).
  • Plan for extra cutting and hardware on steep areas.

Start with the Fence Cost Calculator and refine after selecting your slope approach.

Adding a Gate (Posts, Hardware, and Layout)

  • Measure opening width and confirm swing direction.
  • Plan stronger posts and appropriate hardware.
  • Adjust budget for latch/hinges and reinforcement.

Use the Fence Cost Calculator to account for gate-related cost impacts.

Frequently Asked Questions About Fence Estimates

How do I measure total fence length accurately?

Measure each run between corners and add them together. Include returns and offsets, and measure gate openings separately for planning. Use the Fence Cost Calculator to estimate budget from total length.

What affects fence cost the most?

Material type, height, total length, number of posts, gates, slope/terrain, and labor rates are major drivers. Use the Fence Cost Calculator for a planning estimate.

How do I calculate fence post spacing?

Post spacing is typically planned using on-center spacing, with corner/end posts anchoring each run and line posts filling the span. For picket layouts, use the Picket Fence Calculator.

How deep should fence posts be?

Depth depends on fence height, soil conditions, wind exposure, and local requirements. Use the Fence Post Depth Calculator for planning guidance, then verify locally.

Does slope change fencing material needs?

Yes. Sloped yards may require stepped or racked sections that affect post placement and cutting. Plan for extra time and materials in steep or uneven areas.

How many pickets do I need for a picket fence?

Picket count depends on fence length, picket width, and spacing. Use the Picket Fence Calculator to estimate pickets and spacing.

Should I check property lines and local rules before building a fence?

Yes. Confirm boundaries and local fence rules (height, setbacks, HOA requirements) before purchasing materials or digging.

Do I need to locate underground utilities before digging fence posts?

Yes. Always locate underground utilities before digging post holes using your local utility locating service and follow safe digging practices.

Does this page replace professional fencing advice?

No. These tools provide planning estimates only. Always verify measurements, product specifications, and local requirements. Consult a qualified professional for complex terrain, high wind areas, or boundary-related concerns.

Important Estimate Disclaimer

Calculator results are general planning estimates only. Actual materials, costs, and post depth requirements can vary based on soil conditions, wind exposure, fence design, terrain, and local codes.

Always confirm your fence design and requirements before purchasing materials. Confirm boundaries and locate underground utilities before digging. Consult a qualified professional for structural, compliance, or boundary-related concerns.
