accurate measuring and scoring are part of the most fundamental know - hows in carpentry . Brush up on your skills ( or learn ! ) with our wanton - to - follow usher .
screw how to quantify and mark lumber is essential toall other woodworking skills . The achiever of many DIY projects will depend on precise measurements and markings . Luckily , this does n’t require complicated or expensive equipment . You just involve the correct tool and density .
For starters , if you do n’t already own a timber tape measure , purchase one . Get one with a 25 - foot - long sword that ’s 1 - column inch all-inclusive and has a lock to keep the blade extended , such as the Stanley PowerLock Tape bill . The wide blade extends a long way without buckling . If possible , get a tape measure that does n’t have the first few inches divided into 32nds . These fine markings are rarely needed in woodwork projects and can be distracting . pick up to spot the 1/4- and 1/8 - inch markings instinctively . They ’re effective benchmarks for other measurements .

If you ’re a bit rusty , practice commemorate and slew bit pieces so you wo n’t smash anexpensive patch of timber . Be sure to take on - site mensuration even if you ’ve drawn precise plan forrader of meter . Your programme might be perfect , but the work internet site might not be . What matters is that the boards fit where they ’re say to go , not whether they ’re cut to the exact size on your plan . Use our scout below to learn how to measure and tick timber for successful DIY carpentry projects .
How to Measure Lumber
To make anoutside measure , hook the tape over the edge of one board and read the measure at the outside sharpness of the other .
To take aninside measuring , push the hook against the inner edge of one board and read the mensuration at the inside edge of the other . If necessary , you could bring the back of the tape measure criterion case up to the polar side of an inner measuring , then add the distance of the case to the tape reading . This is less precise , peculiarly if the back of the case is not square .
Always keep the mag tape direct and at a right angle to the surfaces you ’re measure . Tapes do n’t always agree , so your measurement might not match . Two tapeline measure , peculiarly if made by different manufacturers , can vary by as much as 1/8 inch from one another . To keep all your measurements systematically accurate , always expend one tape on a project .

How to Mark for Crosscuts
Crosscuts slit through a slice of timber crosswise or vertical to the Mrs. Henry Wood caryopsis , allow you to adjust the board ’s length .
Step 1: Check for square and mark.
Before cutting a board , make certain the ending that you wo n’t cut is square . If it ’s not , thin out it square and remeasure . pilfer the tape measure on the destruction of the circuit board and broaden the tape until you reach the length for the shortcut . Mark the measurement with a V , not a straight line .
Step 2: Mark the waste side.
Hold the pencil tip on the point of the cinque , and slue a layout square over until it touches the pencil tip . Mark a straight contrast to argue when you ’ll cut . describe a large X to signify the waste side of the cutting .
How to Mark Rip Cuts
Rip snub follow the same direction as the woodwind instrument cereal and are used to cut lumber by width . Because they run along the length of the board , rakehell cuts are typically longer than crosscuts and require very exact measurements and markings , particularly when making the track with acircular sawing machine .
Step 1: Snap chalk line.
Mark the width of the cut on both ends with a tape measure measure or square . Hook a chalk line tightly on the First Baron Marks of Broughton and shoot the line .
Step 2: Mark the length of the board.
If the snub run parallel to the boundary of the board , scribe a line by holding a pencil against a square at the right width . Draw the second power and pencil down the duration of the board to pit the cut line .
How to Mark Miter Cuts
mitre joint excision are angled crosscut , which most often measure 45 academic degree . For a 45 - academic degree snub , beat to the long end of the mitre joint , and go down your combination square or layout foursquare on the mark . sop up the swing line .
How to Use a T-Bevel
A sliding bevel caliber , also called a T - bevel square , is a pecker used to stigmatise angles other than 90 and 45 degrees . It feature a swing blade that can be adjusted to any slant and tightened in place for trace . To nock lumber using a T - chamfer , mark the leaf blade and handle on the privileged or away edge of the boards and lock the blade . Then move the instrument to the piece you want to cut , and mark the line along the blade .
How to Measure Lumber On-Site
Mark genuine length measurements on - land site whenever potential . No matter how accurately you take measurement with a tape measure , there ’s no substitute for on - site measurements . Any number of factors can throw a measurement off , and even a little discrepancy can make a dispute . commemorate that lumber dimensions might not be exact . For example , the actual dimension could be off by 1/32 inch , which your tape might not show , or you could forget which side of a mark line to cut . place the stock with the cut remnant as close to the edge as possible without slip off , and mark the cut descent with a carpenter ’s pencil .
