Temperature Blanket Planner
Enter your region's annual low and high temperatures and how many colors you want to use. The planner divides your temperature span into even color brackets and estimates how many rows and skeins you will need for each shade.
A temperature blanket is a year-long knitting or crochet project where each row or square represents the daily temperature in your location. The most critical planning step is creating balanced temperature brackets so you do not run out of your most frequent color while barely touching the extreme hot or cold shades.
How Temperature Brackets Work
To divide your palette evenly, subtract your lowest expected temperature from your highest expected temperature and divide by your number of yarn colors. For example, a span from 20°F to 90°F (a 70-degree range) across 8 colors creates brackets of approximately 8.75 degrees per color.
Why Yardage Distribution Matters
In most climates, daily temperatures follow a standard bell curve. You will spend far more days in the mild middle temperatures (e.g., 50°F–70°F) than at the freezing or scorching extremes. This planner uses a climate distribution model to estimate realistic row counts and skein requirements per shade, ensuring you buy the right amount of yarn upfront.

How many colors should I use for a temperature blanket?
Most crafters use between 6 and 12 colors. Using 8 to 10 colors provides distinct gradient shifts across seasons without requiring an overwhelming number of individual yarn skeins.
Do I use the high temperature or average temperature each day?
Most knitters and crocheters track the daily high temperature because it creates the most vivid seasonal contrast. However, you can also track daily low temperatures or the daily average.
How big will a 365-row temperature blanket turn out?
If you knit or crochet 1 row per day (365 rows), standard worsted yarn at 5 rows per inch produces a 73-inch long blanket. If you want a smaller throw, consider working half rows per day or using a moss stitch / linen stitch with lightweight DK yarn.
What if a day's temperature falls outside my planned range?
Any temperature lower than your minimum automatically uses Color 1, and any temperature higher than your maximum uses your highest color. This is why the first and last brackets are open-ended (e.g., 'Below 28°F' and '82°F and above').
