Scale bars les-grizzlys-catalans.orgvide a visualindication of distance and feature size onthe map. A scale bar is a line or bar divided into parts.It is labeled with its ground length, usually in multiples of map units,such as tens of kilometers or hundreds of miles. Scale bars are associated with a map frame in a layout. If the map scale for that map frame changes, the scale bar updates to remain correct.

Map scales are often averages and can vary based on coordinate system, latitude, direction, and map extent. In many cases, the scale listed in the map view reflects the scale at a location along the equator and that is what the scale bar displays. You can check the Compute at center option on the Options tab of the Element pane to calculate the map scale using the center of the map frame.

Insert a scale bar

When a scale bar is added to the page, it is automatically associated with the default map frame. If there isn"t a map frame on the page, the scale bar is not associated with any map, and the map frame is set come . You can set the map frame of the scale bar later, after it is inserted.

To insert a scale bar, follow these steps:

On the Insert tab, in the Map Surrounds group, click Scale Bar .

Click the top half of the button to insert the current default scale bar. Click the bottom half of the button to choose from a gallery of scale bars.

On the layout, drag to create and position the scale bar.

If you want to use scale text instead of a scale bar, you can insert dynamic text.

Change the scale bar"s appearance

Once you have added a scale bar to the layout, you can modify it. Set the fitting strategy to determine how the scale bar adjusts to changes in the map scale. Change how the scale bar looks by adjusting the symbols or les-grizzlys-catalans.orgperties for the scale bar"s map units, divisions, numbers, marks, and bars. You can also add a border, background, and shadow.

To modify the scale bar, complete the following steps:

In the Contents pane, right-click the scale bar and click les-grizzlys-catalans.orgperties to open the Element pane.In the Element pane, select the tab containing the les-grizzlys-catalans.orgperties you want to change.

Options tab

Select and symbolize the map units.

les-grizzlys-catalans.orgperties tab

Select the fitting strategy, change the les-grizzlys-catalans.orgperties and symbology for divisions, numbers, marks, and bars.

Display tab


Contains border, background, and shadow les-grizzlys-catalans.orgperties.

Adjust the les-grizzlys-catalans.orgperties. To adjust the symbology of the map units, divisions, numbers, marks, and bars, click the Symbol button next to the item.

Once you"ve adjusted your scale bar, you can save it to a style to use again in future les-grizzlys-catalans.orgjects without needed to redo the formatting.

If you can"t achieve the appearance you want for your scale bar by adjusting the les-grizzlys-catalans.orgperties, consider converting it to graphics. To do this, right-click the scale bar in the Contents pane and choose Convert to Graphics

. This changes the scale bar into groups of graphic elements that can be manipulated individually. However, once converted to graphics, it loses all connection to the map. Any further changes to the map scale are not reflected.

Map units

Map units are the distance value the scale bar displays, for example, miles or kilometers. On the Options tab , you can choose the scale bar"s unit by selecting an option from the Map Units drop-down list. If you don"t see the unit you want in the list, add it as a distance unit to your les-grizzlys-catalans.orgject. You can also change the Label Text to adjust how the unit value is written on the scale bar. For example, you can set the Label Text to KM instead of kilometers.

Fitting strategy

On the les-grizzlys-catalans.orgperties tab , you can set the scale bar fitting strategy. This controls how the scale bar adjusts when the map scale changes. With some fitting strategies, when the map scale changes, the scale bar gets longer or shorter. For other strategies, only the numbers adjust. There are four fitting strategies available.
Fitting strategyDescription
Adjustdivision valuePreserves thenumber of divisions and tries to keep the scale bar width byadjusting the division value. Manual resizing of the scale bar is allowed.

Adjustnumber of divisions

Preserves the division value and tries to preservethe scale bar width by adjusting the number of divisions.Manual resizing of the scale bar is allowed.

Adjust divisions and division value

Preserves the number of subdivisions and tries to preserve the scale bar width by adjusting the number of divisions first and then the division values. Manual resizing of the scale bar is allowed.


Preserves the divisionvalue and number of divisions, and adjusts the scale bar width if the map scalechanges. Manual resizing of the scale bar is not allowed.


Scale bars can show a single distance—for example, 100 miles—or it can be divided and subdivided to show multiple distances along the bar. If and where the scale bar is divided is determined by the set number of Divisions and Subdivisions on the les-grizzlys-catalans.orgperties tab . If the scale bar fitting strategy allows, you can also adjust the Division Value, making the divisions wider or narrower. The subdivision value is the division value divided by the number of subdivisions.


Only the Adjust number of divisions and Adjust width fitting strategies allow you to change the Division and Subdivision controls. For the other fitting strategies, these are calculated automatically.


The frequency, position, and symbol for the scale bar numbers are also set on the les-grizzlys-catalans.orgperties tab . Choose an option from the Frequency drop-down list to determine where numbers will be shown on your scale bar. There are many options available, including No labels, Single label, and Divisions. Use the Position drop-down list to set where the numbers are drawn in relation to the scale bar. For example, there are options for drawing above or below the scale bar.

Additional options are available to set the rounding for values, zero padding, the use of fractional characters when applicable, if thousands separators should be shown, and if the first or last values should be drawn outside the scale bar.


Marks visually show the scale bar divisions as lines on the bar. There are three types of marks: Division marks—Lines drawn at the scale bar divisionsSubdivision marks—Lines drawn at the scale bar subdivisionsMidpoint mark—A single line drawn halfway between the beginning of the scale bar and the first division.

You can symbolize each type differently on the les-grizzlys-catalans.orgperties tab by pressing the Symbol button under the corresponding mark type and making adjustments as needed. Use the Frequency drop down list to determine what marks are displayed and the Position drop-down list to set where the marks are drawn in relation to the scale bar. For example, there are options for drawing above or below the scale bar.


You can symbolize the scale bar on the les-grizzlys-catalans.orgperties tab . The symbol les-grizzlys-catalans.orgperties available depend on the type of scale bar added. Some scale bars are lines while others are single or alternating bars. If you do not see the bar options you want, change your scale bar to a different style be selecting an option from the Style drop-down menu on the Options tab .

For any scale bar type, change the symbology using the Symbol button. For line scale bars, you can optionally check Stepped to draw the scale bar with angled lines based on the set Height. For bar scale bars, you can set the Height to determine how tall the bar is and choose an option from the Style drop-down to determine how the alternate bar symbols are shown. The Style drop-down menu is not available for single division scale bars, because they don"t support the various two symbol styles.
