This result is a specification — 0.953 cords — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Frequently asked questions

What's a 'face cord'?
A face cord (or 'rick') is a stack 4 ft high by 8 ft long, but only as deep as one log length (commonly 16 in) — it's a fraction of a full cord, roughly 1/3 for 16 in logs, and is often confused with a full cord in casual sales.
Does wood species affect how much heat a cord provides?
Yes — dense hardwoods (oak, hickory) provide significantly more heat per cord than softer woods (pine, fir), even though they occupy the same stacked volume.
Does stacking tightness affect the count?
Yes — a loosely stacked or round (unstacked, thrown) pile contains noticeably less actual wood than a neatly stacked one of the same outer dimensions, due to air gaps.
