Check Square Calculator: Diagonal Check for Foundations & Decks

Fri, 07 Aug 2026 22:00:41 +1000

A square corner is the quiet hero of every build. Get the foundation square at the start and every wall, every door frame, every cabinet falls into place naturally. Get it wrong and you spend the rest of the build cutting tapered packers to make doors close. The Chippy Tools check square calculator is the simplest possible Pythagoras app — enter a length and width, get the expected diagonal, and compare it to the diagonal you measure on site. If the two match, the work is square. If they don’t, fix it before pouring concrete or nailing off boards.

Concrete Calculator: Slabs, Post Holes & Columns

Fri, 07 Aug 2026 22:00:41 +1000

Calculating the required amount of concrete you need to order for your construction project is necessary. There is no point ordering the wrong amount of concrete in today’s economic climate. Product costs are going up, so you don’t need to add to it by ordering too much concrete (or too little).

That’s where the concrete calculator comes in. Conveniently stored on your phone in your pocket, the app allows you to calculate the exact amount of concrete that you need for your next project. You will never stuff up ordering the correct quantity of concrete again.

Decking Calculator: Boards, Joists, Bearers & Screws

Fri, 07 Aug 2026 22:00:41 +1000

A deck looks like a rectangle of boards but it’s really four layers stacked on top of each other — boards, joists, bearers, and posts on footings. Get any one layer’s spacing wrong and the math for the others falls apart. The Chippy Tools decking calculator handles the math for all four layers from a single deck length × width input — and returns the area, board count, linear metres of boards (with and without 10% waste), joist count, total joist length, bearer count, total bearer length, and even an estimate of the screws you’ll need.

Diagonal Calculator: Find Rectangle & Square Diagonals

Fri, 07 Aug 2026 22:00:41 +1000

Understanding Diagonals

Diagonals are secret pathways cutting through rectangles and squares, connecting opposite corners while dividing shapes into two congruent right triangles. Whether you’re working with a rectangle, a square, or any shape that accommodates a right angle triangle, understanding diagonals is essential.

Key Concepts

Rectangles and Squares

A rectangle is a four-sided shape with opposite sides that are equal in length but not necessarily equal to each other. It includes two diagonals, each slicing the rectangle into two congruent right triangles. A square is a special rectangle where all four sides are equal, meaning its diagonals are equally profound.

Dumpy Level Calculator: Fast Reduced Level Calculations

Fri, 07 Aug 2026 22:00:41 +1000

What is a Dumpy Level Calculator?

A dumpy level calculator helps surveyors and construction professionals determine reduced levels and height differences between points on a building site. By entering your benchmark RL and staff readings, you can quickly calculate the reduced level at any measured point, whether your benchmark is on the ground or elevated on a fence.

Key Features

- Simple data entry for benchmark RL and staff measurements

Equal Spacing Calculator

Fri, 07 Aug 2026 22:00:41 +1000

Figuring out even spacing calculations doesn’t need to be complicated. Whether you’re working in feet, inches, centimeters, or millimeters, our spacing calculator app will handle the math for you. This mobile tool helps you determine the perfect distance between objects, members, or posts in seconds, allowing you to focus on completing your project.

What is an Equal Spacing Calculator?

An even spacing calculator is a specialized tool designed to help you determine the precise distance between evenly distributed objects across a given distance. The calculator returns accurate measurements for any project requiring uniform spacing, from fence posts to picture frames, shelf brackets to landscaping elements. This essential tool eliminates the guesswork and reduces errors that can occur with manual calculations.

Fence Picket Calculator: Picket Count, Spacing & Posts

Fri, 07 Aug 2026 22:00:41 +1000

Building a fence looks simple from the curb — a row of pickets nailed to a couple of rails — but the maths catches a lot of people out. Get the picket spacing slightly off and you end up with a stupid 12mm offcut at the last post, or a fence that bows because the gaps were tight in summer and dried out wide by autumn. The Chippy Tools fence picket calculator does the arithmetic for you in metric or imperial, so the pickets divide evenly, the gaps stay consistent, and the fence reads as one continuous run from corner to corner.

Gravel Calculator: Estimate Volume, Tonnage & Coverage

Fri, 07 Aug 2026 22:00:41 +1000

Below is your comprehensive guide to using our Gravel Calculator for all your construction project needs. Whether you want to know how much gravel you need for a driveway, estimate the volume of crushed stone, or simply compare different types of gravel, this page has you covered.

Introduction

Welcome to our all-in-one Gravel Calculator—your perfect companion to handle any size of construction project that involves gravel, pea gravel, coarse gravel, or crushed stone. We created this tool to help you calculate gravel volume in either metric or imperial units. By doing so, you can easily work out the amount of gravel you need in cubic yards or in the cubic meter system.

Raked Wall Calculator: Stud Lengths & Angles Made Easy

Fri, 07 Aug 2026 22:00:41 +1000

Roof Pitch & Rafter Calculator: Rise, Run, and Rafter Length

Fri, 07 Aug 2026 22:00:41 +1000

A roof’s pitch determines almost everything else about it — the rafter length, the snow and wind loads, the choice of roofing material, the cost of timber, and the height of the building. Get it right at the framing stage and the eaves line up, the gable ends close cleanly, and the tiles or sheets sit at their designed angle. Get it wrong and you spend three days re-cutting birdsmouths. The Chippy Tools roof pitch calculator does the math for you in metric or imperial — punch in the rise and run, and the app returns the pitch ratio, the pitch angle in degrees, and the rafter length for any straight roof slope.

Running Measurements Calculator

Fri, 07 Aug 2026 22:00:41 +1000

Running measurements are one of the most common calculations required in construction, building and many other related fields. Chippy Tools can calculate all the running measurements you need in a fraction of the time, allowing you to spend less time making calculations and more time focusing on the work that needs to be done.

The app provides an easy-to-read table with all of the running measurements you will need, allowing you to compare the results. We know that in many instances numbers may not add up equally, so we provide all calculations to a very high level of accuracy (millimetres in 2 decimal points for metric users). Your experienced expert judgment and understanding of what needs to be done is better than the app, which is simply just another tool in your tool belt.

Soil Calculator: Estimate Volume for Gardens & Beds

Fri, 07 Aug 2026 22:00:41 +1000

Looking to tackle major landscaping projects or simply refresh your garden? Our comprehensive soil calculator is here to help you figure out exactly how much soil you need. From small flower beds to large-scale yard transformations, having accurate soil estimates ensures you plan efficiently and avoid unnecessary costs.

Understanding your target soil volume is the first step to success. With a single click, you can calculate soil volume for any space and precisely determine the soil needed for flowerbeds, vegetable patches, or orchard expansions. This streamlined approach helps your plants experience the best growth possible.

Stair Calculator: Stringer, Rise, Run & Treads

Fri, 07 Aug 2026 22:00:41 +1000

A staircase looks like one of the simplest things in a house — a row of steps from one floor to the next — until you start measuring. Get the rise height a few millimetres off and the staircase fails inspection or feels uncomfortable underfoot. Get the stringer cut wrong and you waste a 4-metre length of structural timber. The Chippy Tools stair calculator does the arithmetic for you in metric or imperial, accounts for the maximum and minimum rise rules in your region, and returns the stringer length, going length, base length, and tread count for any straight-flight staircase from a 600mm garden step up to a 3-metre full storey rise.

Triangle Calculator: Sides, Angles, Hypotenuse & Miter

Fri, 07 Aug 2026 22:00:41 +1000

The right triangle is the most useful shape in carpentry — every roof pitch, every stair stringer, every diagonal brace, every miter cut, every square-up check is a right triangle dressed up in different language. Get comfortable with the three-side three-angle relationships and most of the math on a job site evaporates. The Chippy Tools triangle calculator does the trig and Pythagoras for you in metric or imperial — punch in any two values and the app returns the missing sides, angles, area, and perimeter.

Wainscoting Calculator: Panel Spacing, Stiles & Rails

Fri, 07 Aug 2026 22:00:41 +1000

Wainscoting looks deceptively simple on a magazine page — a row of panels marching evenly between skirting and chair rail — until you measure your wall and realise it doesn’t divide cleanly into any obvious panel size. Get the panel widths slightly off and you end up with a 78mm filler in one corner that nobody can un-see. The Chippy Tools wainscoting calculator does the arithmetic for you in metric or imperial, so the panels divide evenly across the wall, the stiles line up at corners and door openings, and the wainscoting reads as one balanced run from end to end.
