Jacks Foal & Pony Expand-O Size Guide

The Expand-O-Blanket and Expand-O-Sheet (both original and 200g insulated versions) share the same size ladder for miniature horses, ponies, and fast-growing foals.

Size	Girth Measurement
Medium	30"–37"
Large	38"–45"
Extra Large	46"–53"

How to measure
The front closure and belly band overlap for maximum size adjustment, so a wide range is covered by each size. The Extra Large size features an additional surcingle strap and adjustable fit strap at the withers.

Sizing notes: Measurements shown are manufacturer-published figures and apply identically to the Expand-O-Blanket, 200g Expand-O-Blanket, Expand-O-Sheet, and 200g Expand-O-Sheet.

The 5/A Baker Expand-O-Blanket in 200g is made for miniature horses, ponies and fast-growing foals — the original 5/A Baker triple weave fabric with a 200 gram layer of Curvofil IV insulation added. The front closure and belly band overlap the body, so the same blanket keeps fitting as the horse fills out.

Best for

Foals and youngstock through colder weather than the uninsulated version covers
Miniature horses and ponies needing a fit that adjusts as they grow
Stable use where extra warmth is wanted
