MS Paint Selection Tools

Selection tools mark part of a picture so you can work on that part alone. Move a tree to a new spot, delete a stray mark, or copy a logo to another file. Paint offers two main ways to select: rectangle and free-form.

Why Selection Matters

Imagine cutting a shape from a sheet of paper with scissors. The scissors separate one piece from the rest. Selection tools play the same role on the canvas. Everything outside the marked area stays safe while you edit the inside.

Rectangle selection versus free-form selection Rectangle: grabs the box Free-form: follows the shape

Rectangle Selection

Click the Selection button and choose Rectangle selection. Drag from one corner to the opposite corner. A dashed box appears around the area. The box includes everything inside, including background color.

Free-form Selection

Choose Free-form selection from the same menu. Hold the mouse button and trace around the object. Close the outline by returning to the starting point, and release the button. The dashed line follows your path. Free-form selection captures irregular shapes such as clouds, leaves, and faces.

Useful Selection Commands

Select All

Press Ctrl and A to select the whole canvas. Use this command before a big move, a full copy, or a quick clear.

Invert Selection

Choose Invert selection to flip the selection. Everything that was outside becomes selected, and the original area becomes unselected. The command helps when it is easier to select the object and then reverse the choice to edit the background.

Delete

Press the Delete key to erase the selected area.

Move a Selection

Place the pointer inside the dashed area until it changes to a four-way arrow. Drag the selection to a new spot. Paint leaves a hole filled with the background color behind. Hold Ctrl while dragging to leave a copy in the old spot and move a duplicate.

Resize a Selection

Small squares appear on the edges of a rectangle selection. Drag a square to stretch or shrink the contents. Hold Shift to keep the proportions steady.

Selections and the Eraser

Inside a selection, tools such as the Eraser, Brush, and Fill only affect the selected area. Use this behavior to paint inside a shape with no spill across the edges.

Tips for Better Selections

  • Zoom in before tracing small objects with free-form selection.
  • Take your time on curves, because quick moves create jagged outlines.
  • Use Ctrl and Z to retry a failed selection.
  • Click outside the selection to release it.

Common Problems

The Selection Brings the Background Along

A rectangle grabs everything inside its box. Use free-form selection to hug the object tightly, or use Remove background after selecting the area.

A White Hole Appears After Moving

Paint fills the old position with the background color. Draw over the hole or copy and paste instead of cutting.

The Selection Disappears

Clicking anywhere on the canvas outside the box ends the selection. Draw it again to continue.

Practice Exercise

Draw a simple scene with a house, a tree, and a sun. Use a rectangle selection to move the house to the left. Trace the tree with free-form selection and copy it three times to create a small forest. Invert the selection to change the sky color without touching the objects.
