Using PDF Measuring Tools 

These instructions relate to Adobe Reader XI. To download the latest version of free Adobe Reader 

software navigate to http://get.adobe.com/uk/reader/ 

The tools will only work on PDF documents created in Adobe Reader 7 or later so these will not work 

on some older archived documents on Public Access. 

Measuring Toolbar 

To access the measuring toolbar select Edit, Analysis, Measuring Tools 

The majority of our plans are scanned and as such the Snapping tools won’t work so ignore these. 

Measuring Tools 

The tools are as follows: 

Distance Tool 

Click the first point, move the pointer to the second point, and then click again. The 

measurement appears in the Measurement Info Panel 

Perimeter Tool 

Click each point you want to measure. Then double click the last point, or hold the 

pointer over the last point and click. The measurement appears in the Measurement 

Info Panel. 

Area Tool 

Click each point you want to measure. After you have clicked at least two points, click 

the first point to complete the area measurement. The measurements appear in the 

Measurement Info Panel. Scale Ratio 

When you have selected the tool that you require you will need to enter the scale ratio. 

The most commonly used scales on our plans are as follows: 

1:50 Set the scale to 1cm = 0.5m 

1:100 Set the scale to 1cm = 1m 

1:200 Set the scale to 1cm = 2m 

1:500 Set the scale to 1cm = 5m 

1:1000 Set the scale to 1cm = 10m 

1:1250 Set the scale to 1cm = 12.5m 

1:2500 Set the scale to 1cm = 25m 

When using the above rations the distance/area will be displayed in metres. All plans should have 

the scale clearly marked on them. 

Useful Tips 

 To constrain the measurement lines to increments of 45 hold down the Shift key 

 To discontinue a measurement right click and choose cancel measurement 

 To delete a measurement markup, click it with the Measurement Tool and press Delete 

More Measuring Tool Options 

Use the right click menu to set measuring tool options: 

 Change scale ratio: change scale ration (such as 3:2) and the unit of measurement on the 

drawing areas 

 Change markup label: add or change text that appears with the measurement 

 Disable/enable measurement markup: when enabled, the measurement lines disappear 

when you measure another object or select another tool 

 Turn ortho on/off: when enabled measurement lines are orthographic only 

 Show/hide rulers: show or hide vertical and horizontal rulers on the page 

 Snap to page content/don’t snap to page content: turn all snap enables on or off
