How to Restring a Ukulele
Restringing looks fiddly the first time but it's a simple, repeatable process: off with the old, tie in the new, then patiently stretch and retune until it settles.
When to restring
Strings that look frayed, discolored, or feel grimy, or that sound noticeably dull and won't stay in tune even after settling in, are ready to be replaced. Many players restring on a schedule — roughly every six months to a year of regular playing — rather than waiting for strings to fail outright.
Step 1: Remove the old string
Loosen the string fully at the tuning peg until it's slack, unwind it, then untie or slide it free at the bridge. Change strings one at a time rather than removing all four at once — it keeps the neck under more even tension and means you'll never lose track of which string goes where.
Step 2: Tie it at the bridge
Most ukulele bridges use a simple tied knot rather than a ball end. Thread the new string through the hole or under the tie-bar, loop it back over itself, and cinch it into a secure knot that won't slip loose under tension.
Step 3: Thread and wind at the tuning peg
Feed the string through the tuning peg's hole, leave a little slack for a couple of wraps, and turn the peg so the string winds down neatly toward the headstock. Aim for clean, non-overlapping wraps so the string tracks true across the nut.
Step 4: Stretch and retune, repeatedly
Bring the string up to pitch, then gently stretch it by pulling it away from the fretboard along its length, and retune. Repeat this a handful of times — new nylon and fluorocarbon strings drift out of tune quickly at first, and stretching speeds up how fast they settle.
Common questions
How often should you restring a ukulele?
Roughly every six months to a year for regular play, or sooner if strings look frayed, sound dull, or won't hold tuning even after stretching in.
Why won't my new ukulele strings stay in tune?
Nylon and fluorocarbon strings stretch noticeably when new and take longer to settle than steel strings — expect frequent retuning for the first several days.
Do you tie ukulele strings or use ball ends?
Most ukulele bridges use a tied knot rather than a ball end, so restringing means threading the string through the bridge and tying it off before winding it up to the peg.
Should you change all four strings at once?
Generally yes — changing them one at a time keeps the bridge and neck under even tension, and your set ages and sounds consistent together.
