Have you ever found a crochet blanket pattern only to discover that it’s not your desired size? Or maybe a crochet baby blanket pattern caught your eye, but it was a kingsize bedspread you needed? You can resolve this and many more problems with our blanket size calculator.

This easy-to-use online tool will help you count how many stitches and rows you need to make a blanket size you want. In this article, you will learn how to use it and what to use it for.

What is the Blanket Size Calculator?

This calculator tells you how many rows and stitches you need to achieve the desired blanket size. For example, you can resize a baby blanket pattern to fit a double bed, or the other way around. You can also use it as a regular crochet stitch calculator to determine how many stitches you need for a project.

This tool will be useful for crocheters, knitters, and other crafters who want to create blankets for specific needs or preferences.

The calculator won’t work with blankets worked in the round, or with granny square blankets.

How to Use the Blanket Size Calculator

To make the calculations, you need to know three things:

  1. What type of yarn you want to use in your blanket.
  2. What stitch pattern you want to use in your blanket.
  3. Dimensions of the blanket you want.

Then, make a swatch using the yarn and pattern. Measure it and count the rows and number of stitches across. Next, choose the metric or imperial system, and put the numbers in the calculator. You will then be able to see common blanket sizes or use the “Custom” option to set your own width and height.

The calculator will show you the results in a blanket size chart.

Factors to Consider

Types of blankets and their standard sizes

Different types of blankets, such as throws, comforters, and bedspreads, have varying standard sizes. Understanding these sizes is the first step to creating a versatile home accessory.

Our calculator has a built-in table of standard blanket sizes, ranging from tiny loveys to California King size bedspreads. This way, you can compare the dimensions and choose your favorite.

Size of bed or mattress

Remember that the size of the mattress shouldn’t be the same as the size of the bed. You should always count in the overhang, which may vary depending on your preferences.

Common bed sizes include twin, full, queen, and king, each requiring different sizes of blankets for optimal coverage.

Consider how much coverage you want the blanket to provide. Some people prefer a blanket that fully covers the bed, while others may prefer a smaller throw blanket for added warmth or decoration.

Personal preferences and needs

Crocheting a blanket is a big project, so consider any personal preferences or special requirements before starting.

  • Room size and decor – measure the bed to ensure the right blanket size. Consider color palette and pattern, so that it fits in the room.
  • Climate and season – heavy blankets will be perfect for winter, while lightweight lacy ones will come in handy during summer months.
  • Functionality and versatility – consider where and when you will use the blanket. Will it be a decorative bedspread only, or a multifunctional throw?
  • Special needs – individuals with mobility issues may prefer a lighter, or smaller blanket, while others may prioritize warmth and coziness.

Tips for accurate measurements

Do these things achieve the most accurate calculations:

  • Use a flexible measuring tape – soft, flexible measuring tape allows for accurate measurements around curves and irregular shapes.
  • Double-check measurements – measure both the width and the length of the bed, then write the numbers down.
  • Account for overhang – if you want the blanket to drape on each side, add extra length or width to accommodate it.
  • Round up – when in doubt, always go with bigger dimensions than smaller ones.


In summary, the blanket size calculator is a valuable tool for crocheters and knitters alike. Put the information into the calculator and use it to come up with the perfect recipe for your blanket. This calculator will surely help you save time and money on your crochet blanket projects.


Can I use a crochet calculator for both knitting and crochet projects?

Yes, you can use this calculator for knitting projects as well. The initial measurements are based on the swatch, so it doesn’t matter if it’s knitted or crocheted.

That said, remember that knits are more stretchy than crochet projects. It may play a significant role in the overall size, especially if you are using heavy yarn.

Can a crochet calculator account for different yarn weights and hook sizes?

If you want to see how the same crochet stitch works with different yarn type or hook size, you have to make a new swatch and measure it. Unfortunately, there’s no easier way to do it.

How accurate are the measurements provided by crochet calculators?

The accuracy of the calculator depends on various factors. The precision of the input data, the complexity of the project, or your style of crocheting, all can affect the final size of the product.

Generally, this crochet stitch calculator provides reliable estimates, but you should keep in mind its limitations.

Are there any tips for using a crochet calculator for beginners?

Firstly, familiarize yourself with the calculator by reading how it works and inputting some test measurements. See how the results are presented and how to read them.

Secondly, block the swatch before measuring it, because otherwise it may be distorted. To achieve the most reliable results, use the same yarns and tools as in the final project.
