A 7–8 inch (about 19 cm) wig fits MSD and SDM heads. Learn how to measure, choose between W-174N, W-188N, and W-155N, and care for the fiber.
Quick answer
Measure your doll's head circumference first; if it falls between 7 and 8 inches (about 19 cm), a size 7–8 MSD/SDM wig is the correct fit. W-174N, W-188N, and W-155N all share that measurement, so choose between them by color and price rather than size.
Why head shape matters as much as circumference
A circumference measurement tells you the size range, but head shape affects how a wig sits. A rounder head may fill out the cap, while a narrower head can leave a little extra room at the sides. If your doll's head is close to the 8-inch upper limit, expect a snugger fit; near 7 inches, the same wig may sit slightly looser. The catalog only lists the 7–8 inch range, so use your own measurement as the deciding factor rather than assuming every MSD or SDM head is identical.
Heat-resistant fiber is not a license for high heat
These wigs use heat-resistant fiber, which can endure heat up to a certain temperature, but the catalog does not specify that temperature. Treat heat styling as a cautious, low-heat operation and test on a hidden strand first. The same fiber can be damaged by prolonged heat, so brief passes are safer than holding a tool in one spot. If you are unsure, style with cold methods such as finger shaping or a damp set.
Color transfer is a real risk, not a rare defect
The catalog warns that wig color may stain the doll's surface. This is a general caution for these wigs, not a sign of a faulty product. Dark or saturated colors carry more risk, so if you plan to leave a wig on for long periods, check the head under the cap periodically and consider a protective liner. Remove the wig for storage rather than leaving it on the doll indefinitely.
MSD and SDM wig questions, answered
- How do I measure my doll's head for a 7–8 inch wig?
- Wrap a soft tape measure around the widest part of the head, just above the ears and across the forehead. If the result is between 7 and 8 inches (about 19 cm), a 7–8 MSD/SDM wig is the right range. Measure twice to confirm. Write the measurement down so you can compare it with future wigs.
- Do W-174N, W-188N, and W-155N fit the same dolls?
- Yes. All three list the same fit: Yo-Midi, SD Midi, and Mini Super Dollfie at approximately 19 cm / 7"–8". None is sized differently from the others, so pick by color and price.
- Why does the catalog warn about staining?
- The wig color may transfer to the doll's surface. This is a general caution for these wigs. Limit continuous wear, check the head periodically, and store the wig off the doll when not in use. A removable liner can add a layer of protection if you change wigs often.
- What does 'teased' mean on these wigs?
- Some wigs are teased, a process where short, frizzy hair is added inside to increase volume. That volume is built in, so avoid over-brushing the interior, which can flatten the tease.
- Can I use heat tools on these wigs?
- The fiber is heat-resistant up to a certain temperature, but the catalog does not state that temperature. Use low heat, test on a hidden strand, and keep the tool moving. Cold styling is the safer default.
- How should I care for an MSD wig day to day?
- Brush gently from the ends upward, store the wig on a stand or in a bag away from direct sun, and avoid leaving it on the doll for weeks at a time. If the fiber looks dry, a light mist of water and finger shaping is gentler than heat.
Three wigs in the same size range
- W-174N: W-174N fits Yo-Midi, SD Midi, and Mini Super Dollfie, with a measurement of approximately 19 cm / 7"–8". If your doll is in that head-size range, this wig is a direct fit without resizing.
W-174N - W-188N: W-188N also fits Yo-Midi, SD Midi, and Mini Super Dollfie at approximately 19 cm / 7"–8". It shares the same fit range as W-174N, so your choice between them comes down to color and budget.
W-188N - W-155N: W-155N fits the same doll types at approximately 19 cm / 7"–8". A third color option in the same size, useful if the other two shades do not suit your doll.
