About the Horse Blanket Calculator

The Horse Blanket Calculator started with a familiar barn problem: standing at the gate on a cold, wet evening, phone in one hand, trying to remember whether a 35-degree night with a body-clipped horse means a midweight or a heavy. The printed charts taped inside tack-room doors are a decent start, but they assume one tidy scenario - an unclipped horse, a dry day, no wind - and most real evenings are not that tidy.

So we built the version we wanted: type in the temperature, say whether the horse is clipped and how heavy its coat is, tick off the things that actually change the answer - wind, rain, age, an empty paddock with no shed - and get a clear weight back. No sign-up, no app to download, and it works on a phone in the dark with cold thumbs.

What makes it different

Static retailer charts handle the average horse on an average day. The two things they handle worst are clipping and weather, and those are exactly the variables that put a horse at risk of being cold. A body-clipped horse has had its insulation shaved off; a horse standing out in wind-driven rain loses heat far faster than the thermometer suggests. This calculator builds those factors in, shifting its recommendation a category warmer when the conditions call for it, instead of leaving you to do the math in your head.

Where the numbers come from

The baseline is a temperature-by-clip matrix assembled from widely used blanketing guides - SmartPak's blanketing guide, Schneiders' blanketing basics, and university extension and veterinary sources. Those references broadly agree: clipped horses need roughly one to two weights heavier than unclipped horses at the same temperature, and wet, wind, or low body condition all push warmer. We kept the matrix visible on the homepage so you can check our work, not just trust it.

Who it is for

Horse owners, leasers, working students, and barn staff who make the blanket call every day through fall and winter - especially anyone managing a clipped sport horse, a hard keeper, or a senior who feels the cold. It is meant for quick, practical decisions, not as a replacement for knowing your own horse.

An honest limit

No calculator can feel your horse's chest or watch it shiver. This one offers general guidance to get you in the right ballpark; you still have to check under the blanket and, for any horse that is sick, very old, or struggling to hold condition, talk to your veterinarian. It is free, it runs entirely in your browser, and it is built by people who would rather over-explain a blanket weight than have a horse stand out cold.
