Exact size and position controls are useful when Google Slides objects must follow a repeatable specification. They provide more precision than dragging by eye. Confirm the measurement unit and whether the object should keep its proportions before entering values.
Open size and position
In the desktop editor, select the intended object and choose Format > Format options. Open the available Size & Position controls described in Google’s arrangement guidance. Check the selected object’s outline so you do not resize a neighboring shape or an entire group unintentionally.
Enter values with the right units
Review width, height, and position values before changing them. Use the measurement-unit preferences when you need a familiar unit. If the object should retain its shape, inspect Lock aspect ratio before changing a dimension.
For an image, arbitrary independent width and height changes can distort the subject. For a group, resizing can affect several components, so consider whether the full group or only one element needs adjustment.
Verify geometry and readability
Check the object against guides, neighboring items, source captions, titles, and the slide edges. Present the slide to ensure that the numerical specification produces a readable result. Exact values do not guarantee optical balance when an image includes empty space or a text box contains internal padding. Record the intended object dimensions if they are part of a reusable design. Review the slide after later wording changes because text growth can create an overlap even when the original object position remains numerically correct.
