The difference between 30-35% could make for a sucky day... :whistlingfor me I always use 30-35 % of the SF...works everytime.
when i do a walk through and count it..comes damn close.
Case in point - today's job. 585sf flooring, 220lf shoe. Master suite with dual walk-ins and a guest bedroom with typical 2-6x8 closet. 585/3.5=167+50=217. 14 sticks of 16' = 224. Dead on the money. Works majority of the time. When I walk a job a can get a feel of how much to add or subtract from the original formula.A formula that has always worked for estimating purposes (used only for my own supply estimates, actual used will vary and we bill what we actually use) is square footage divided by 3.5. Adjust up or down depending on how open or cut up the layout is. Example 1000sf area to install = 285lf of base/shoe/cove base. If it's wide open I'll drop 50ft off or add if its cut up. Through the years I can count on one hand the number of times I had to bring more the next day or run out to get a job finished. More times than not it's a tad heavy.
3.5 formula wouldn't have worked on the house we're working on... when you add variables like hallways and closets, it would've been off by 13%... and that's assuming no screw-ups...Case in point - today's job. 585sf flooring, 220lf shoe.

Probably had alot of baseboard heat..Here's my formula: i measure how much i need.
30-35% of footage? We did a 2900' a few weeks ago, needed 440' of shoe... 30-35% wouldn't have even been close
Not really.. figuring and actually buying are 2 different things..this works in estimating..when doing the job you can give an accurate count for purchase.Unless alot of baseboard,archway,doorways etc the count works pretty well.The difference between 30-35% could make for a sucky day... :whistling
Because as I mentioned, you get a feel for how much to add or subtract based on how open or cut up it is. It's called experience :thumbsup: We're talking in context of estimating purposes, like as in "do I need to throw another bundle on the truck or am I good" - "nah we have a thousand footer tomorrow and Wednesday, it's not cut up at all a bundle and a half should get it (our bundles are 256lf ). We're not saying the formula will get you dead nuts for billing purposes but you'd be surprised how accurate you can be and not have to run around the house measuring or doing a takeoff. If it don't work for you don't use it. I've been using this method for over 10 years, like I said it's cost me maybe 3-4 trips to get more shoe out of thousands of jobs - I'd say that's a pretty good success rate.i dont have the slightest clue how its possible for their to be a formula as to how much shoe you need.. you can have a small 1800 sq ft house but its chopped up into a bunch of small rooms which means requiring a ton of shoe.. or you can have a large house that is open concept.. because of that you wont need as much. thats why floor sq footage means nothing.. i measure up how much i need and add 10%
