But not everyone is fortunate enough to have the space (or the pleasantly&nbsp;supportive better half) required to store a couple hundred board feet&nbsp;of lumber.<\/p>\n<p>If you must buy material according to the needs of&nbsp;each project, know this: figuring out&nbsp;how much&nbsp;board footage to get is an exercise in <em>estimation<\/em>.&nbsp;You have to do a little math and a little guessing, and the result is just an approximation. &#8220;This project is going to require about 11 board feet.&#8221;<\/p>\n<h2>1. Start with a&nbsp;Project Idea, Plan or Sketch<\/h2>\n<p>Your plan can be as simple as a napkin sketch or as sophisticated as a SketchUp or magazine plan, or anything in between. It should essentially&nbsp;answer the question: <em>what&#8217;s the overall size of this project?<\/em><\/p>\n<p>You just need to have a concept of the general size. Then you can step your way into the details.&nbsp;Once you know, for example, that you want to make an end table about 20&#8243; square (or whatever) you&#8217;ll be able to determine the size of its parts, and therefore how much wood it&#8217;s going to require . . . and ultimately how deep into your budget you&#8217;ll need to dive.<\/p>\n<p><p>Invalid Displayed Gallery<\/p><\/p>\n<p>If you start with a&nbsp;sketch or &#8220;napkin plan&#8221;, it will&nbsp;probably start out crude, awkward, or kind of embarrassing. That&#8217;s okay, it&#8217;s just a draft. You&#8217;ll revise and refine things as you get your hands wrapped around the project. A plan from a magazine or book will have a lot of the heavy lifting done for you.<\/p>\n<h2>2. Make a Parts List<\/h2>\n<p>Now you&#8217;ll have to start putting some thought into things. Use a spreadsheet (<a href=\"https:\/\/www.woodworkerssource.com\/help\/Project-Planner-Board-Feet-Calc2.xlsx\" target=\"_blank\" rel=\"noopener noreferrer\">download this free template if you want<\/a>), or an old fashioned piece of paper and pencil, start jotting down the individual parts to your project. Let&#8217;s use a basic end table as an example: top, legs, and aprons. Put down the sizes of each of those parts, like this would work:<\/p>\n<table border=\"1\" cellspacing=\"10\" cellpadding=\"10\">\n<tbody>\n<tr>\n<td style=\"background-color: #fce3ac;\">\n<h5>Part<\/h5>\n<\/td>\n<td style=\"background-color: #fce3ac;\">\n<h5>Rough<br>Thickness<\/h5>\n<\/td>\n<td style=\"background-color: #fce3ac;\">\n<h5>Final<br>Thickness<\/h5>\n<\/td>\n<td style=\"background-color: #fce3ac;\">\n<h5>Width<\/h5>\n<\/td>\n<td style=\"background-color: #fce3ac;\">\n<h5>Length<\/h5>\n<\/td>\n<td style=\"background-color: #fce3ac;\">\n<h5>Quantity<\/h5>\n<\/td>\n<td style=\"background-color: #fce3ac;\">\n<h5>Net<br>Board Footage<\/h5>\n<\/td>\n<\/tr>\n<tr>\n<td><strong>Top<\/strong><\/td>\n<td>4\/4<\/td>\n<td>3\/4&#8243;<\/td>\n<td>20&#8243;<\/td>\n<td>20&#8243;<\/td>\n<td>1<\/td>\n<td>&nbsp;2.78<\/td>\n<\/tr>\n<tr>\n<td><strong>Legs<\/strong><\/td>\n<td>6\/4<\/td>\n<td>1-1\/4&#8243;<\/td>\n<td>1-1\/4&#8243;<\/td>\n<td>18&#8243;<\/td>\n<td>4<\/td>\n<td>&nbsp;.78<\/td>\n<\/tr>\n<tr>\n<td><strong>Aprons<\/strong><\/td>\n<td>4\/4<\/td>\n<td>3\/4&#8243;<\/td>\n<td>2-1\/2&#8243;<\/td>\n<td>17-1\/2&#8243;<\/td>\n<td>4<\/td>\n<td>&nbsp;1.25<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"padding-left: 60px;\"><em><span style=\"color: #ff0000;\">TIP:<\/span> To calculate board feet: rough standard thickness X actual width X actual length divided by 144.&nbsp;&nbsp;Use the thickness of the material you intend to start with, not end with. For example, the 3\/4&#8243; top will start from 4\/4 lumber. The legs will start from 6\/4 lumber. This is because you must start with 4\/4 lumber in order to achieve a final 3\/4&#8243; thickness; likewise, you must start with&nbsp;6\/4 lumber to achieve a final 1-1\/4&#8243; thickness.&nbsp;<a href=\"https:\/\/www.woodworkerssource.com\/shop\/calc.html\">See this page for more about board feet.<\/a><\/em><\/p>\n<h2>3.&nbsp;Add It Up, then Apply a Waste Factor<\/h2>\n<p>Now you&#8217;ll&nbsp;determine how much 4\/4 to buy, how much 6\/4 to buy (etc.) So first add up the board footage of the parts that come from the same thickness of lumber.&nbsp;In the example here, you should come up with:<\/p>\n<p style=\"padding-left: 60px;\"><em>4.03 board feet of 4\/4<\/em><\/p>\n<p style=\"padding-left: 60px;\"><em>.78 board feet of 6\/4<\/em><\/p>\n<p>That&#8217;s the exact amount that the parts equate to.<\/p>\n<p>Now add&nbsp;some extra &#8211; consider multiplying by at least 1.5 or 2. After all, to end up with those parts, you have to start with boards that are larger. Round off to the nearest whole number, too. You&#8217;ve arrived at <em>about<\/em> the board footage&nbsp;you&#8217;re going to buy, or a target amount, so there&#8217;s no sense in talking in terms of decimals or fractions at this point. It&#8217;s not the precise amount, as that is determined once your&nbsp;boards are selected and measured. Since boards in the lumber pile vary in width and length, you may be aiming to pick up 8 board feet and what you end up selecting could be something more like 7.89 or 8.62 or 10.18. It just depends on what the lumber pile provides and which pieces appeal to you. But at least you have a really good idea of what your project needs.<\/p>\n<table border=\"1\" cellspacing=\"10\" cellpadding=\"10\">\n<tbody>\n<tr>\n<td style=\"background-color: #fce3ac;\">\n<h5>Lumber<br>Thickness<\/h5>\n<\/td>\n<td style=\"background-color: #fce3ac;\">\n<h5>Net<br>Board Footage<\/h5>\n<\/td>\n<td style=\"background-color: #fce3ac;\">\n<h5>Approximate<br>Footage&nbsp;to Buy<\/h5>\n<\/td>\n<\/tr>\n<tr>\n<td><strong>4\/4<\/strong><\/td>\n<td>&nbsp;4.03<\/td>\n<td>8<\/td>\n<\/tr>\n<tr>\n<td><b>6\/4<\/b><\/td>\n<td>&nbsp;.78<\/td>\n<td>3<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Now that you&#8217;ve approximated your the footage you need&nbsp;you can get a pretty good idea of what the project will cost you. And if you&#8217;ve made an adequate estimation, you&#8217;ll have plenty of material to work with to create a project you&#8217;ll be proud of. You know what&#8217;s worse than buying too much wood for a project? <em>Not having enough to complete it.<\/em><\/p>\n<p>If a factor of 2 seems like a lot,&nbsp;there&#8217;s more to think about than just the parts of your project. To build a really great project, you need enough material to:<\/p>\n<ol>\n<li>Mix\/match grain patterns or color<\/li>\n<li>Cut around parts of boards you don&#8217;t like<\/li>\n<li>Test your stains or finishing process<\/li>\n<li>And, believe it or not, you&#8217;ll probably make a mistake once or twice and need to cut an extra part.<\/li>\n<\/ol>\n<p>In a real life example, let&#8217;s say you want to cut a board down to 4&#8243; x 48&#8243; from a piece that was 6&#8243; x 48&#8243;. That&#8217;s not terribly uncommon, nor is it unreasonable. Yet, that&#8217;s 33% waste &#8211; or in other words a 1.5 waste factor without a defect to work around.<\/p>\n<p>After&nbsp;you build a few projects, you&#8217;ll discover how realistic it is to not just plan for enough wood, but more than enough.<\/p>","protected":false},"excerpt":{"rendered":"<p>&nbsp; 1.
