Quick answer: To stabilize a brush in ibis Paint X, select the Brush tool, open the brush’s parameter settings and raise the Stabilizer value. Low values (around 1 to 3) remove small jitters while keeping the stroke responsive; middle values (4 to 6) smooth long curves and line art; high values (7 to 10) produce very clean lines at the cost of noticeable lag. The setting is saved per brush, so set a high value on your inking brush and a low one on your sketch brush. For perfectly straight or circular lines, use the Ruler tool instead of pushing the stabilizer to maximum, and for the shakiest hands, pair a moderate stabilizer with stroke taper and a slightly larger canvas.
Shaky lines are the most common frustration for anyone drawing on a phone or tablet. Fingers wobble, cheap styluses jitter, screen protectors drag, and a quick confident stroke on paper turns into a nervous zigzag on glass. ibis Paint X includes a stabilizer that smooths this out, but it is tucked into the brush settings where many users never find it, and setting it wrong introduces a different problem: a brush that feels like it is being dragged through syrup.
This guide explains exactly where the stabilizer lives, how to stabilize an ibis Paint brush for different kinds of work, what the numbers mean, how to combine stabilization with taper, rulers and canvas size for even cleaner results, and how to manage your brush list, including deleting brushes you no longer need. For a look at which brushes come well tuned out of the box and which benefit most from stabilization, see the roundup of the best ibis Paint X brushes.

What the Stabilizer Actually Does
A stabilizer averages the position of your pen over a short trailing window and draws the line through the averaged path instead of the raw input. Small, fast deviations, which is what hand tremor and touch-sampling noise look like, are smoothed away, while the overall direction of the stroke is preserved.
The cost is lag. The more positions the app averages, the further the drawn line trails behind the pen tip. At low settings the delay is imperceptible. At the highest settings the line visibly chases the pen, corners get rounded off, and quick flicks are shortened because the stroke ends before the average catches up.
That trade-off is why there is no single right value. Sketching needs responsiveness; inking needs smoothness; lettering and clean curves often want the highest setting you can tolerate.
Where to Find the Stabilizer in ibis Paint X
- Tap the tool selector at the bottom-left and choose Brush.
- Tap the brush icon again to open the brush list.
- Select the brush you want to stabilize, then open its parameter settings (usually an edit or gear control beside the brush, or a second tap on the brush preview).
- Scroll the parameter list to find Stabilizer (sometimes grouped with correction or smoothing settings). It is a numeric slider, typically ranging from 0 to 10.
- Drag the slider and watch the stroke preview at the top of the window, or close the window and test directly on the canvas.
Because the value is stored with the brush, every brush in your list can have its own stabilizer level. Changing it on your pen does not change it on your airbrush.
How to Stabilize an ibis Paint Brush: Step by Step
- Duplicate the brush first. In the brush list, duplicate the brush you plan to adjust so you keep an unstabilized version for sketching. Rename the copy, for example “Pen (stable 6).”
- Open the copy’s parameter settings.
- Set a starting value of 4. This is a sensible middle ground for most line art on a tablet.
- Draw three test strokes on the canvas: a long slow S-curve, a short fast flick, and a sharp zigzag with corners.
- Judge the result. If the S-curve still wobbles, raise the value by 1 or 2. If the flick gets cut short or the zigzag corners turn into round bumps, lower it by 1 or 2.
- Repeat until the long curve is clean and the corners are still sharp enough. Most people settle between 3 and 7 for inking.
- Enable initial and final taper (force fade) on the same brush. Taper hides the slightly shortened stroke ends that stabilization produces and gives line art a professional finish.
- Leave the sketch brush low. Set your rough sketching brush to 0 to 2 so it stays fast and loose. Switch brushes when you move from sketch to ink rather than changing the value back and forth.
Recommended Stabilizer Values by Task
| Task | Suggested range | Why |
|---|---|---|
| Thumbnails and rough sketching | 0 to 2 | Speed and gesture matter more than clean lines |
| Refined pencil sketch | 2 to 4 | Takes the edge off jitter without dulling the hand |
| Comic and manga inking | 4 to 7 | Clean long curves, still allows controlled corners |
| Hair strands and long flowing lines | 6 to 9 | Long single strokes benefit most from heavy smoothing |
| Lettering and logo work | 7 to 10 | Precision over speed; combine with slow strokes |
| Painting and blending | 0 to 3 | Smoothing adds nothing to soft brushes and only adds lag |
| Drawing with a finger | 5 to 8 | Fingers are far less precise than a stylus |
| Drawing with a basic capacitive stylus | 4 to 7 | Rubber-tip styluses add their own wobble |
| Active stylus with pressure | 2 to 5 | Hardware already reduces jitter |
Other Settings That Make Lines Cleaner
The stabilizer is one of several tools that fight shaky lines. Combining them lets you keep the stabilizer moderate and avoid lag.
Initial and Final Taper (Force Fade)
Found in the same brush parameter window, taper thins the start and end of each stroke over a set distance. It makes overlapping strokes blend together, so you can build a long line from two or three shorter, more controlled strokes instead of one shaky one.
Minimum Thickness
A low minimum thickness lets light pressure produce a hairline, which means tentative passes barely show and confident passes dominate. This is a form of visual stabilization: the eye reads the dark, deliberate line and ignores the faint wobbly one.
Canvas Size and Zoom
Drawing zoomed in magnifies hand movement relative to the line, which looks shaky. Zoom out slightly and draw with larger arm movements; wobble shrinks relative to the stroke length. A canvas of 2,000 to 3,000 pixels on the long edge gives enough resolution to zoom out while keeping lines crisp.
Rulers
For straight lines, circles, ellipses and symmetrical designs, the Ruler tool (straight, circular, elliptical, symmetry, array and perspective-type guides depending on version) constrains the stroke to the guide. No stabilizer value matches a ruler for geometric lines, and rulers add no lag.
Palm Rejection and Stylus Settings
In the app’s general settings, enable palm rejection or stylus-only drawing if your device and stylus support it. Accidental palm contact and double touch registration look like jitter and no stabilizer can fully correct them.
Device and Surface
Matte screen protectors add friction that steadies the hand for many people. A drawing glove reduces drag and stray touches. Resting the heel of the hand on the screen and pivoting from the wrist for short strokes, or from the elbow for long ones, improves control more than any software setting.
Stroke Technique That Works With the Stabilizer
- Draw at a steady speed. The stabilizer averages positions over time, so uneven speed produces uneven smoothing. A consistent medium pace gives the cleanest result.
- Commit to the stroke. Hesitation produces the micro-corrections that stabilization is trying to remove. Plan the line, then draw it in one motion.
- Ghost the line first. Hover the pen over the path once or twice without touching before drawing. This is standard practice for inkers on paper and works just as well on glass.
- Break long lines into overlapping segments with taper enabled, rather than relying on a maximum stabilizer for one enormous stroke.
- Use undo freely. A two-finger tap undoes the last stroke in ibis Paint. Redrawing a line is faster than fixing it.
Common Stabilizer Problems
| Problem | Cause | Fix |
|---|---|---|
| Line lags far behind the pen | Stabilizer too high | Lower by 2 or 3; use rulers for geometric lines |
| Corners come out rounded | High stabilizer averaging across the corner | Lower the value or draw corners as two separate strokes |
| Fast strokes end short | Stroke finishes before the averaged path catches up | Enable final taper; slow the stroke slightly; lower the value |
| Lines still shaky at 10 | Palm or double-touch interference, or zoomed in too far | Enable palm rejection; zoom out; use larger arm movements |
| Stabilizer resets when switching brushes | The value is per brush | Set it on each brush you ink with, or duplicate one tuned brush |
| Brush feels dead or unresponsive | High stabilizer combined with high min thickness | Lower both; stabilization should be felt only on long curves |
Managing Your Brush List
Once you start keeping stabilized and unstabilized copies, the brush list grows quickly. A few habits keep it usable.
Naming
Put the stabilizer value in the name, such as “Ink 6” or “Sketch 1,” so you know at a glance which copy you are holding.
Ordering
Enter the list’s edit mode and drag your most-used brushes to the top. Keep sketch, ink and shading brushes grouped.
How to Delete ibis Paint Brushes
- Open the Brush tool and the brush list.
- Enter edit mode (often an edit button, a long press on a brush, or a swipe on the brush row depending on version).
- Select the brush and tap the delete or trash control, then confirm.
- If you remove a default brush and want it back, look for a restore-defaults option in the brush list menu or app settings.
Before deleting a custom brush you spent time tuning, generate its QR code and save the image. That lets you restore it later without rebuilding the settings. The guide on how to add brushes to ibis Paint covers importing from QR codes if you ever need to bring one back.
Stabilizer Setups for Three Kinds of Artists
Phone Artist Drawing With a Finger
Set the inking brush to 6 to 8 with taper on and min thickness low. Work zoomed out and build lines from short overlapping strokes. Use the ruler for anything straight. Keep a sketch brush at 2 for layout.
Tablet Artist With a Basic Stylus
Inking at 4 to 6, sketching at 1 to 2, shading brushes at 0. Enable palm rejection if available. A matte protector or glove helps with drag and stray touches.
Tablet Artist With a Pressure Stylus
Inking at 3 to 5, since the hardware already filters jitter. Rely more on min thickness and pressure curve for line variety, and reserve higher stabilizer values for hair, long contours and lettering.
FAQs
How do I stabilize my brush in ibis Paint X?
Choose the Brush tool, open the brush list, select a brush and open its parameter settings, then raise the Stabilizer slider. Values of 4 to 7 suit most inking; keep sketch brushes low.
Why is there still lag after stabilizing?
Lag is the cost of stabilization. Lower the value, use the ruler for straight or curved geometric lines, and rely on taper and overlapping strokes instead of maximum smoothing.
Does the stabilizer apply to every brush?
No. It is saved per brush. Set it individually on each brush you want smoothed, or duplicate one tuned brush and vary its other settings.
How to delete ibis Paint brushes?
Open the brush list, enter edit mode, select the brush and tap the delete control. Default brushes can usually be restored from a restore-defaults option if removed by mistake.
What is the best stabilizer setting for line art?
Most artists land between 4 and 7 for inking on a tablet, higher when drawing with a finger or a basic stylus, lower with a pressure-sensitive pen.
Can I stabilize lines without the stabilizer?
Partly. Rulers constrain geometric lines, taper hides shaky ends, zooming out reduces visible wobble, and drawing from the elbow at a steady speed improves control. Most clean line work combines these with a moderate stabilizer value.
Final Thoughts
Stabilizing an ibis Paint brush is a per-brush setting found in the parameter window, and the right value depends on the job: low for sketching and painting, middle for inking, high for lettering and long flowing lines. Pair it with taper, a low minimum thickness, rulers for geometry and a steady stroke, and most of the shakiness disappears without the dragging feel of a maxed-out setting. Keep separate tuned copies of your core brushes, name them by value and back them up as QR codes. For brushes that respond especially well to this kind of tuning, the guide to ibis Paint X brushes for clean line art and shading is a useful starting list.
